Summary of the issue you are facing:
I’m using nested AD groups for authentication. All users from parent group and nested child group have been imported to nextcloud successfully. Users in parent group can login and authenticate with their AD credentials. Users from nested group can be seen in Nextcloud with names and details. But users from the nested group cannot login.
The global security groups are organized like this:
Top group (parent): nc_users
Contains a few users. All these users can authenticate. Nextcloud is working fine.
Nested group within nc_users: nc_group1
nc_group1 contains 20 users. All are visible in accounts view with names and details. LDAP sync seems sucessful. LDAP configuration checks are all green. User counts correct.
None of the nested users can authenticate.
I followd the documentation for nested AD groups. But something seems to be missing or wrong.
This is my LDAP configuration:

Nextcloud
Nextcloud works as expected for users in the top group.
Web Browser
Issue is unrelated to browsers and client OS.
TIA
