My homelab has two chained routers, which creates two different networks. In the login screen, type your LDAP username and password and you should login just like when you use your local account on pfSense. This provides a backup if your phone breaks, or gets lost. After login, go to Services >> DNS Resolver and scroll down to the Host overrides table and click on Add and fill in as follows: Click on Save and Apply changes for the changes to take effect. Therefore, I'm trying to connect the Synology to LDAP … We call it LDAP-as-a-Service. Test the DNS entry by going to Diagnostics >> Ping and enter the full name of your Synology device and click Ping. Next, go to Settings tab, click on Enable LDAP server and put the full domain name that matches the domain on your SSL certificate on the FQDN text box. This has the disadvantage of splitting the password management, so we wanted to fix it. As shown in the ‘Your Samba File Server/NAS’ visualization above, an IT admin will configure the server to have its authentication deferred to an external LDAP directory, instead of utilizing the servers own locally stored user accounts. I want to SSH into it using key-based authentication, but that seemed not supported by default. This can be achieved with this LDIF snippet: Again, we need to grant our LDAP service bind access to these ‘new’ attributes. This article will guide you through and explain how to join the Synology NAS to the LDAP directory server. Both pfSense and Synology need to have the same certificates installed. This is how I managed to get Linux machines to authenticate against it. LDAP Server User’s Guide 5 Chapter 1: Set up LDAP Server Enable LDAP Server After the LDAP Server package is installed, go to Main Menu > LDAP Server. This work is a collaboration with my colleague Markus Opolka (@martialblog). In the new group dialog, type pfsense_admins as Group name and click Next. A list with at least three OUs will be listed. Local. Go to the LDAP Configuration tab, then Connection Settings to configure the connection settings with the QNAP NAS. Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Configuring pfSense authentication through Synology LDAP server, configure SSL certificates on your pfSense, configure SSL certificates on your Synology, configure pfSense + UDM Pro to work together through this post, Configuring a OpenVPN server on your pfSense using LDAP authentication – Thiago Crepaldi. IT admins simply point the NAS authentication path to the cloud hosted directory service, then enable LDAP Samba authentication within the DaaS platform. You no longer need to key in accounts individually, which can save a … Consider hosting your private dedicated Synology network access server with us. By default, you can enable only username-password based authentication for OpenVPN in the GUI. Download config backup file from the Synology; Change file extension from .cfg to .gzip; Unzip the file using 7-Zip or another utility that can extract from gzip archives The missing link is resolving the full domain name of the Synology server (e.g. Ideally, Synology NAS can be joined to Azure AD in a similar fashion as a Windows 10 device, benefiting from the ability to use the Azure Active Directory domain for user authentication, and, if possible, fileshare / webdav permissions, without the need for setting up AAD Domain Services. Now you have a running LDAP server with a new user which belongs to the pfsense_admins group. Adjust the following on the Synology NAS: According to development team, LDAP User's configuration is not as same as Domain User's configuration, also their authentication method are different. Now that pfSense can recognize users from Synology’s LDAP server, we have to create a local group that will be used to map the remote group on LDAP. At Authentication Server field select the LDAP connection as opposed to Local database. As pfSense doesn’t know names resolved by UDM Pro, we will create a static rule for this. As a Synology DiskStation can merge into any existing LDAP directory service easily, it could greatly reduce the time spent on creating numerous sets of accounts for different services. Learn More About LDAP Authentication for NAS Devices. What we have to do here is 1) to create a firewall rule on the UDM-Pro to allow an incoming connection from pfSense to passthrough UDM Pro, then we need to 2) forward port 389 from UDM Pro to your Synology NAS with LDAP server running and finish off by 3) creating a DNS entry on the pfSense to manually resolve the Synology hostname to the UDM Pro IP. These NAS devices are cost-effective and easy to implement. I am a keen amateur photographer with a lot of photos taking up a lot of space and a Synology DS916+. Lightweight Directory Access Protocol (LDAP) is a directory that stores information for users and groups on a central server. Synology NAS. At this stage, any connection that is coming from your pfSense towards UDM Pro using TCP port 389 is accepted by the firewall. Now you can connect to your LDAP and browse the LDAP database to see its contents. However, my NTLM audit did not pick up anything. Note that although authentication was successful, your LDAP user doesn’t belong to any group recognized by pfSense. In this post I explain how I made it work. Authenticating Windows 10 drive mapping with LDAP users I’m using jumpcloud.com to provide LDAP users on my Synology. This user is a member of groups: ‘. DLS’s dedicated hosted storage solution leverages Synology’s DiskStation Manager (DSM) operating platform to deliver a comprehensive suite of applications and cloud storage services. One more thing: we strongly discourage using Synology’s Web-UI to modify the ownership of directories since it discards the modes of the files. SSO client configuration on synology is under Control Panel - Domain / LDAP - SSO Client. Worst case scenario is that I can add LDAP authentication to the NAS subdomain which I've already done for a few of my reverse proxy destinations, but that seems unnecessary, as the Synology already has it's own authentication scheme. A confirmation screen will be displayed and you can Apply to finish the process. Finish configuration by clicking Apply. If authentication is still not functioning, here are two tips for debugging: https://support.microsoft.com/en-us/help/243330/well-known-security-identifiers-in-windows-operating-systems, http://pig.made-it.com/samba-accounts.html, http://www.citi.umich.edu/projects/nfsv4/crossrealm/libnfsidmap_config.html, https://www.freeipa.org/page/Howto/Integrating_a_Samba_File_Server_With_IPA, https://aput.net/~jheiss/samba/ldap.shtml, https://bgstack15.wordpress.com/2017/05/10/samba-share-with-freeipa-auth/, https://www.redhat.com/archives/freeipa-users/2015-August/msg00137.html, Go to “IPA Server” and create a new role “File Server”, Create a new privilege “Samba Authentication”, Add a new permission “Read Samba Attributes” to this privilege, Select the various Samba attributes listed, Add the newly created role to the bind account, In the FreeIPA UI: Extend the previously created role “File Server”, Create new privilege “Kerberos Authentication”, Add new permission “Read NFS Attributes” to this privilege, Note: Since these attributes are not native to FreeIPA, you have to type, Enable the verbose debug logs in Control Panel -> File Services -> SMB -> Advanced Settings -> Collect Debug Logs, log into the NAS via SSH and look at the logs under. Consider watching the webinar below for an indepth look at the architecture behind LDAP authentication to Samba-based file servers like Synology NAS. Once installation is finished, click on Open to begin the configuration. Go to System >> User Manager >> Groups, click on Add and do as follows: Click on Save and test the group mapping by going to Diagnostics >> Authentication as described before. Port: The default setting is 389. Network attached storage (NAS) devices from Synology, QNAP, and FreeNAS, among many others, are a popular choice for on-prem storage. Login to your Synology NAS, open the Package center, search for LDAP and click on Install button. See user Greenstream's answer in the Synology Forum:. But we don’t want to follow their scheme, therefore we disable the auto-creation of home directories on the NAS and manually create the home directory and set the owner to johndoe@example.com. Here's how to set up Synology NAS authentication with LDAP, powered by Foxpass. Since the NFS LDAP is not included with FreeIPA, get the UMICH schema from http://www.citi.umich.edu/projects/nfsv4/crossrealm/libnfsidmap_config.html (at the bottom of the page) and insert it into /etc/dirsrv/slapd/schema/99nfs.ldif. You need to issue Let’s Encrypt SSL certificates, configure SSL certificates on your pfSense, and finally configure SSL certificates on your Synology that you issued from pfSense. Go to System >> User Manager >> Settings page. I use pGina with Ldap on a Synology Diskstation DS212J, Here are the pGina configuration parameters that work for me. However, doing so will transfer LDAP users' password to Synology NAS in plain text (without encryption), thus lowering the security level. Click on Apply and you should see your new rule listed on WAN rules tab. Take note of Base DN and Bind DN. You can manage LDAP users and groups with this package. Rather, login via SSH and set the appropriate owner with chown. With Google Authentication you are lost if you didn’t record the QR code or manual key at the time you set you the account. LDAP Hosts: Ip address of my NAS LDAP port: 389 Group DN Pattern: cn=%g,cn=groups,dc=ldap,dc=e*****,dc=com Member Attribute: memberUid:2.5.13.2: Pick a password that all your LDAP clients, including the pfSense appliance, will use to bind with the server. Host Name: Key in the IP address of your QNAP NAS. Here is what we found out through a lot of internet research, searching through log files and digging in the configuration. If there is no typo, you should see something like: User authenticated successfully. I have heard it is possible to use SSO with Office 365, (if under Microsoft account you mean actual Microsoft account) but I haven't tried that myself; these folks here though seemed to succeed. Make sure at least pfsense_admins is checked before clicking Next. Port must be 389 and Encryption method must be Use StartTLS extension. If you don’t have this topology, you can skip this section. • The Synology NAS is not a client of any domain or LDAP directory: If the Synology Anyway, given my scenario, my LDAP server is behind UDM Pro, which is a different network from pfSense. The users are being pulled down correctly into the DS 1019+, but the only way I can map a drive from Windows 10 clients is to use the Synology local administrator account. retype) their password in the Web-UI once, then FreeIPA will automatically set the password hash. If you have local users on the Synology NAS, you can manually map the UID (Control Panel -> File Services -> NFS -> Kerberos Settings -> ID Mapping), but then the users are still using the ‘local’ password on the NAS. synology.lan.domain.com) to the UDM Pro IP address. Otherwise, LDAP users will need to enable their computer's PAM support to be able to access Synology NAS files via CIFS. The next screen has a bunch of optional fields that you can fill in as pleased. It’s not so secure, using a certificate based authentication gives you higher security and it can protect against MITM attack.. The steps will include SSL encryption based on Let’s Encrypt certificates. It is important to have a description that explains why it is needed for future maintenance. I’ve opted for this approach as I enjoy Unifi’s powerful Access Points and nice integration with UDM Pro, but I don’t trust them for securing my home, so I delegated security and VPN to pfSense. First, log into Foxpass and do the following: Note your Base DN on the dashboard page. By default, Synology NAS creates the home directory for the user at /home/@LH-${FQDN}/${some_number}/${user}-${uid}. This is a scenario I'm definitely interested in as well. When you click at Save and Test, you should see a dialog in which pfSense succeeds is 1) connecting, 2) binding, 3) fetching organizational units from LDAP server. The next screen shows a list of groups you can join the new user. I noticed this after they provided a diskstation logentry saying NTLM authentication failed. Go to Manage groups tab and click on Create button. See how Secure LDAP simplifies identity and access management for you. At Rules tab, click on WAN and Create new rule and fill in the fields as follows: All the other settings can remain as is. NFS authentication via LDAP and Kerberos was previously working, however we had trouble with the ID mappings. NFS authentication via LDAP and Kerberos was previously working, however we had trouble with the ID mappings.If you have local users on the Synology NAS, you can manually map the UID (Control Panel -> File Services -> NFS -> Kerberos Settings -> ID Mapping), but then the users are still using the ‘local’ password on the NAS. Note you will find a cn=users and cn-groups with the user and group you created before. In this article I’m going to show how to authenticate users on your pfSense using LDAP server powered by Synology DSM. Hi guys I hope you are all well. At this point, a LDAP SSL connection coming from pfSense towards the Synology server should passthrough the UDM Pro. At the time of writing, Synology was on DSM 6.2-23739 Update 2. To access the FreeIPA LDAP database, the Synology DSM NAS needs a service account with a password. After going through all the previous steps, pfSense can reach the LDAP server, which already has a user and group in the database. To test your connection, you can install Apache Directory Studio and configure a LDAP connection to your Synology. This first step can be skipped if you are not using chained routers. It turns out, you need to have SMBv1 enabled on your domain controller, in order to support Integrated Windows Authentication on the diskstation. In the new user dialog, type a username on Name, Email, Password and make sure the box Disable this account is unchecked before proceeding to Next. After login, go to Network >> Settings >> Internet security >> Firewall. Select LDAP Connection under LDAP Browser category and click Next, type a meaning Connection name and the full domain name on the Hostname field (must match the domain name on SSL certificate). wireless router supports RADIUS for authentication, you can set up RADIUS Server and use Synology NAS local system accounts, AD domain accounts or LDAP service accounts to … Since your users probably don’t have the NTPasswordHash attribute set yet, they will have to reset (i.e. Your only choice is reset (non-NAS 2FA accounts may be far more cumbersome to recover). Now that pfSense recognizes your LDAP server and knows which groups to look for authorization, the last step is instructing pfSense to consult LDAP database during user login. at the bottom of the page as we are going to use it, along with FQDN and password. Once installation is finished, click on Open to begin the configuration. Expand vpn / l2tp / remote-access / authentication / radius-server / ip address of radius-server In the example below, the Synology NAS address is 10.10.20.13. At this point, the LDAP server is up and running. But you can only set this in the configuration file of the OpenVPN service, that means you have to login to the NAS via SSH. 利用synology NAS當作LDAP+NFS server建置步驟 張貼者: 2019年9月12日 上午2:47 鄭仲翔 [ 已更新 2019年9月12日 上午2:54] FreeNAS authentication with LDAP, powered by Foxpass. • The Synology NAS is using a static IP address: To avoid clients from being disconnected because of IP address changes of the Synology NAS (domain controller), you need to set up a static IP address on your local area network for the Synology NAS. Cloud authentication for network attached storage solutions is a feature of this hosted directory service. Let’s create a user that will be able to login and manage your pfSense deice by going to Manage users tab and clicking on Create. Server Type: Select "OpenLDAP". At the moment, my way of storing and presenting photos is that I have two (2x) main separately mapped key photo folders on my NAS: Photo Storage Here we see the Shared Secret and the Port Number. I bought a synology NAS at home to store some stuff. This user is a member of groups:  pfsense_admins. The next logical step is making UDM Pro to forward this port to the correct device, which is the Synology device (192.168.1.2 in this tutorial). Centralize data storage and backup, streamline file collaboration, optimize video management, and secure network deployment to facilitate data management. In order to perform the last test, click on Logout icon on the top left corner of screen. Don’t forget to synchronize the LDAP between your LDAP server and your NAS (Control Panel -> LDAP -> LDAP Users -> Update LDAP Data). Let’s start with the firewall rule on UDM Pro. Since the NFS LDAP is not included with FreeIPA, get the UMICH schema from http://www.citi.umich.edu/projects/nfsv4/crossrealm/libnfsidmap_config.html (at … Create an LDAP Binder account with the name 'synology' on the LDAP binders page. Although it is quite straightforward to setup a host and service account in FreeIPA, giving it a simple password that allows it to do a simple bind (without requiring Kerberos) requires a direct change to the LDAP database. Source and Destination settings are the same as before and a meaning Description would be something like Allow ICMP on WAN local (pfSense -> UDM Pro). Allowing pfSense to authenticate users through LDAP is a 3 steps process: After login, go to System >> User Manager >> Authentication Servers and click Add and do as follows: Click on Save and test your connection by going to Diagnostics >> Authentication and do as follows: Click on Test and you should see a message like ‘User authenticated successfully. Authentication Type: The NAS LDAP Server uses a "Simple" authentication type. I wrote this HOWTO, using LDAP on Synology so I could try out the Synology Directory Server. Due to the current AD structure, I do not want the Synology domain-joined (the DC's are in a bit of "workaround" status with a quasi-multi domain setup and until that's solved, domain-joining the NAS isn't an option). Unfortunately, Synology’s documentation on this issue is rather sparse. For debugging, I recommend that you create a similar firewall rule that allows ICMP in the IPv4 Protocol field and Echo request in the IPv4 ICMP Type Name subfield. Now we are ready to configure pfSense. You can configure pfSense + UDM Pro to work together through this post too. Learn More about Connecting Synology NAS to DaaS If you would like to learn more about how to connect Synology NAS to cloud identity management, please drop us a note . Once it is installed, click on the new connection icon, which will start a wizard. Navigate to System -> CA’s and add a new ca; Paste the cert chain into the certificate box, leave the private key and passwords field blank, assign a random whole number to the Serial field (1 works fine). Unfortunately, FreeIPA’s web interface does not allow setting ‘custom’ attributes (like the ones shown above), hence users can no longer be created via the Web-UI (since the attributes are mandatory), but have to be created from the command line: Existing users can be modified with the following LDIF script: Important step: grant your LDAP service bind account access to the relevant attributes! Click on Connection settings and check all three boxes and click Ok. For extra context, here is a brief explanation on what each check box will do on your LDAP server: You can make changes to these selections as appropriate, but I recommend using all three features for a tighter security. Login to your Synology NAS, open the Package center, search for LDAP and click on Install button. Just import the file into another andOTP installation and all is well. Time to populate users and groups to use it on pfSense. You can see an example of this utilizing Synology here on our Knowledge Base. Click Next to get to the confirmation screen, which you can click Apply. Before we begin: we are running Synology DSM 6.1 and FreeIPA 4.4. To modify Mac OS X's settings: Go to Applications > Utilities to open Terminal. So let’s fix that, too! Note: If you have set up port forwarding or firewall rules for your Synology NAS, make sure port 389 (for LDAP connection) and 636 (for LDAP (SSL) connection) are properly configured at Control Panel > External In essence, IT admins can manage access to on-prem Samba file servers and NAS appliances (i.e., Synology, QNAP, and more) with one comprehensive directory service platform in the cloud. Copy/paste it somewhere. Connection Type: Select "Standard LDAP". Release Notes for LDAP Server Description: LDAP Server provides LDAP service with centralized access control, authentication, and account management. Keep Authentication method as Simple authentication and type the Bind DN from you Synology on the Bind DN or user along with the Password and click on Check authentication to make sure authentication is fine and click on Finish afterwards. Go to Settings >> Gateway >> Port forwarding and click on Create new port forwarding rule and fill in as follows: Click on Apply and you should see your new port forwarding rule listed. Click on Check network parameter to make sure your LDAP server can be reached and go to the Next step. Since we migrated our old, hacky LDAP server to a completely new FreeIPA instance, authenticating Samba and NFS users with the new LDAP server (provided by FreeIPA) was no longer possible. User Sync & Authentication: You can sync all the existing Google accounts to Synology NAS and authenticate them in a few steps. As we don’t have that many users, the short-term fix was to locally create the required accounts on the Synology NAS. I use a Windows PC. Make sure you select the correct port number. Administrators can use LDAP to manage users in an LDAP directory and allow the users to connect to multiple NAS servers by using the same username and password. If you did everything right, you should see that the Synology.lan.domain.com was resolved to something like 10.0.0.2 and that there was 0.0% packet loss. Next, go to Settings tab, click on Enable LDAP server and put the full domain name that matches the domain on your SSL certificate on the FQDN text box. It will make pfSense resolve Synology’s name to the UDM Pro IP. We will fix that in the next step.
