I have a few LADP ACLs that are related to ldap groups.
I want to create default pages for each group.
How can I assign a user to a group\site in UMP automatically?
Unfortunately it's not currently possible. The Liferay/UMP-side user doesn't get created in the database until after the first time they log in, so prior to log in, there is nothing to assign to a group. This has been requested in the past and may appear in a future release but it's a limitation of the way we implement the Liferay portal itself so it's not something we can easily accomplish.
