Yes, the current read-only mode for GroupMapper is defacto "unsynced". 
It allows you to add new group memberships, but those memberships are 
saved in Keycloak DB, not in LDAP itself. So the group membership is the 
merge of memberships from DB and from LDAP. Removing group membership, 
which is saved in LDAP throws an exception.

I am going to add new mode "read-only" and rename the current read-only 
mode to "unsynced" to be better aligned with the modes for userStorage.
