Hi and welcome to the forum @dima

There is some older entry here about this https://forum.cloudron.io/topic/1565/make-cloudron-groups-accessible-on-ldap?_=1632754454070

The takeaway for the moment is, that groups are not exposed via LDAP, however some bits on Cloudron side have changed, regarding groups and roles, so maybe we can revisit this if we understand the use-case better.
