[SSSD-users] login with shortname in AD cross realm

Hi, Is it possible to configure SSSD to make possible to login with short names across trusty domains? The sAMAccount name attribute in AD are unique, and all users have Posix attributes assigned so there is no risk for name mismatch between different domains. I use ad provider and all default setting for AD backend(gc_search_enable) ; If use_fully_qualified_names = False only users from client machines native domain can login with shortnames; Users from other domains are "unknown". I can successfully make ldapsearch to Global Catalog in top domain for login names=shortname for users from different domains: ldapsearch -H ldap://ldap.c.example.com:3268 -Y GSSAPI -N -b "dc=c,dc=example,dc=org" "(&(objectClass=user)(sAMAccountName=user))" user = user-a from a.c.example.org user = user-b from b.c.example.org best, Longina
