Group names not changing when name is changed in LDAP


We’ve been making some changes to our active directory namely a few group name changes, however Nextcloud does not seem to see or do anything with these name changes for the group names displayed under users.

Nextcloud version: 12.0.1
Operating system and version: Ubuntu 14.04
Apache or nginx version: Apache/2.4.18 (Ubuntu)
PHP version: PHP 7.0.22-0ubuntu0.16.04.1

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

Yes, but we’ve tried to replicate the issue again after it initially occurred.

Can you reliably replicate it? (If so, please outline steps):

Make an active directory group,
add a user to it, log in with the user,
rename the group in active directory,
log in with the created user,
check the group name with your admin account in the users list.
