Nextcloud version : 24.0.7
Operating system and version : Debian 11. 5 (Yunohost)
nginx : 1.18.0
PHP version: 8.0.26

The issue you are facing:

Few Groups have been created with uppercase, for example like Foo_Group or My_Lovely_Group and also one with an uppercase and a number like Foo66. Some of them have been deduplicated without the uppercase like foo_group and foo66.
The users listed on the group Foo_Group are also in the group foo_group, but I can’t edit them to remove them from this group without uppercase foo_group and I can’t delete these groups…

Is this the first time you’ve seen this error? : Yes

Steps to replicate it:

  1. Create a group Foo_Group and add some users
  2. The users also have a GroupFolder a new group foo_group is created without uppercase.
  3. This new group can’t be edited or remove for users.

Hello, well I found what happens ! In fact, the groups without uppercase have been edited on Yunohost webadmin, so in the LDAP of Yunohost, there are not here from Nextcloud.
