Lost my users after upgrading to 24.07

ℹ️ Support

1

Nextcloud version (eg, 20.0.5): 24.0.7
Operating system and version (eg, Ubuntu 20.04): Debian 11
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.54
PHP version (eg, 7.4): 7.4

The issue you are facing:
I have just run the upgrade from 24.06 to 24.07 via web interface and cmd line.
After the update I was unable to login with my normal account which is LDAP authenticated
Tried logging in with the local admin account and was unable to login until I did a password reset.
Checking the users page throws an error and returns no users

If I go into the LDAP/AD Integration and test the LDAP settings, everything passes and I can validate a user by login or email address

Users LDAP filter
&(|(objectclass=user))(|(|(memberof=CN=cloud-access,,DC=local)(primaryGroupID=))))

Login Attributes
LDAP/AD Username (yes)
LDAP/AD Email Address (yes)
(&(&(|(objectclass=user))(|(|(memberof=CN=cloud-access,,DC=local)(primaryGroupID=))))(|(samaccountname=%uid)(|(mailPrimaryAddress=%uid)(mail=%uid))))

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Run the upgrade
  2. Try login after the upgrade

I just found one issue in the bugtracker when using several LDAP servers:

And there was a fix for NC 24.0.8

(just in general, if there is such a bug just going from one version to the other, it is a good idea to check the bug tracker)
