Bug description

After a fresh install and configuration of the LDAP backend (using occ) verification succeeds using ldap:check-config. Sign-in is possible, however the groups the user is assigned (in fact no LDAP group is recognized) to are not recognized. Neither appear they in group:list nor the Settings UI.

An attempt to force update the group using occ ldap:check-group --update --force succeeds and reports that the group is still available. ldap:check-user --update --force also shows all groups the user has been assigned to, however occ user:info recognizes the user, shows the correct backend and quota but does not show any groups. Also if signed in as the user it is evident that the groups are not recognized indeed.

Going to the LDAP settings and hitting "Verify settings and count the groups" in the "Groups" tab gets rid of all of these problems. Now occ groups:list recognizes the groups as well as occ user:info and the UI.

After having triggered the action once via the GUI adding new groups to LDAP with a subsequent run of ldap:check-group --update --force not only succeeds but also correctly updates users and groups throughout the system without the need to retrigger the "Verify settings and count the groups" action in the UI.

Steps to reproduce

Install nextcloud
Configure LDAP via occ ldap:set-config commands
Verify that groups are available via occ ldap:check-group and do not appear in occ group:list.

Expected behavior

LDAP groups should be available across the system.
