The problem is that users has incorrect user_name, when user is added
via RESTAPI or via webadmin. The user_name has not @domain part.
Even in /users url even in /domains/domain_id/users url.
Only when user is added via engine-manage-domains with -addPermissions parametr
then this user has correct @domain part but only at users tab(/users url in API).
Setting target release to current version for consideration and review. please
do not push non-RFE bugs to an undefined target release to make sure bugs are
reviewed for relevancy, fix, closure, etc.
