Add users from read-only directory to Stash managed groups

As a Stash administrator I would like to create Stash groups and populate those groups with users from our LDAP directory. However our LDAP directory is a read-only directory and when I attempt to add a user from that directory into the group created in the Stash directory I get an error that read-only directory entries can't be added to the group. I can add users that are in the Stash directory to the group so the group is writable.

Without this capability I always need to go back to our IT department to create and manage groups that are used in Stash.
