Hello,

I am encountering an issue with our Nextcloud. Attached is a screenshot of the error message, and the details are included in the ticket titles. The problem affects only some users, not all.

more logs:

-InvalidTokenException Token does not exist: token does not exist
-Renewing session token failed: Token does not exist: token does not exist .
-IDP parameter for the UID not found. Possible parameters are:
[“groups”,“username”,“email”,“Role”]

-Exception Call to a member function addUser() on null in file ‘/var/www/nextcloud/apps/user_saml/lib/GroupManager.php’ line 193

The version of :

-Nexcloud : 28.0.4 .
-SSO & SAML : 6.1.3

Thank you!!

Hi @roynabb, thanks for reporting. The log entry about Call to a member function addUser() on null also has a an id passed as "reqId". Could you paste all lines from the log containing that id completely?

Thanks, unfortunately this is not complete. Please check in the nextcloud.log file in the data directory.

If your issue is reproducible, you may want to try to apply the changes in https://github.com/nextcloud/user_saml/pull/839/files for the file lib/GroupBackend.php (in /path/to/nextcloud/apps/user_saml/), enforce the error, and provide the resulting nextcloud.log. It will contain more information.

Thanks, the first one is probably unrelated, the second one does not give much more info.

#838 (comment) would reveal more (and the proper log file that can also be downloaded from the Logging page).

roynabb · 2024-05-06T08:09:41Z

Hello, thank you for your time and effort.

The previous versions we used without encountering this issue were:

SSO & SAML authentication "5.1.3"
Nextcloud "21."

Following the migration to these versions:

SSO & SAML authentication "6.1.3"
Nextcloud "28.0.4",

We identified the problem as being related to a group on our AD server that contains a space in its name. This issue appears to be caused by the new version of USER_SAML APP. For example, the group "Group1_DATA_2020 & PV- Y&N - XSL-Technicals - RO" worked fine before the migration, but after the migration, it caused this error:

The correct format would be: "Group1_DATA_2020&PV-Y&N-XSL-Technicals-RO".
