When installing and configuring a new/clean installation, the groups defined in LDAP are ignored.
username/passwords do work.
With 17.1 it works and the same configuration was used for 19.1.
I select LDAP for authentication and for account storage.
What do you mean with ignored?
I’m not aware of any changes LDAP wise between 17.1 and 19.1.
Egroupware does not show the groups defined in LDAP
This is working in latest versions.
