LDAP issue - users in AD security group not showing

Nextcloud version (eg, 22.2.0): 22.2.0
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04.3 LTS
Apache or nginx version (eg, Apache 2.4.25): 2.4.41
PHP version (eg, 7.4): 7.4

The issue you are facing:
Hello, Just newly installed and trying to setup for LDAP user access. However, it seemed to me that the users assigned to a security group can’t be visible in Nextcloud. I created a AD security group under a new OU, and assigned some existing users in my AD as the members of this security group, i.e.

cn=userGroup,ou=Nextcloud,ou=heterogeneous system,dc=example,dc=com

in LDAP/AD Integration, I set ou=Nextcloud as the base DN… all configuration OK.

I created a new user, say ‘nextcloud.user’ under the ou=Nextcloud. I have selected nested group in Advanced page, but the settings always found only 1 user, i.e. nextcloud.user
Is there way to make all members inside the ‘userGroup’ visible in NextCloud? Your advices and comments are much appreciated. Thanks.

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