I configured LDAP in Nextcloud and works fine. I’m accessing to Nextcloud with my domain users, using “sAMAccountName” and “userPrincipalName” domain users attribute.
I have configured the Windows shared folder in Nextcloud as a “external storage” with SMB/CIFS protocol in user domain session, using “Login credentials, save in session” option.
This is the question:
If I login in Nextcloud with sAMAccountName attribute ({DOMAIN}{User}), the external storage load correctly and works fine.
If I login in Nextcloud with userPrincipalName attribute (mail format: user@domain), the external storage cannot load correctly.
Is it possible to make any adjustments to make it work?
Currently users access the Nextcloud service using the value of their mail / userPrincipalName attribute, as they do today almost all internet services.
It’s a shame not to be able to use external storage with automatic load with this account login format. But being ldap users …
I had the same problem and figured it out.
The problem is your UPN isn’t saved into the session while logging in.
First you go to Settings -> External storages and choose as authentication method Log-in credentials, save in database
I tried save in session but save in database is the only setting that works.
Next edit this file on your Nextcloud server:
/var/www/nextcloud/apps/files_external/lib/Lib/Auth/Password/LoginCredentials.php
Change: $storage->setBackendOption(‘user’,$credentials[‘user’]);
To: $storage->setBackendOption(‘user’, $uid);
Then go to: Settings -> LDAP / AD integration -> Expert
At “Internal Username Attribute:” enter sAMAccountName
The sAMAccountName will be put into the $uid variable you declared before.
Restart the webserver:
sudo service apache2 restart
Hi, I have the same problem with the current v22. I tried the recommendations above, but after editing the LoginCredentials.php file the website errors and cannot be accessed.
Please let me know if you have a fix for version 22 or 23. Thank you.
