Hi,
Using SSSD 1.14.2 on RHEL6, users from a different than the joined domain
are only resolved when specifying the domain. As an exmaple:
Joined domain "northamerica", the user uniq_user_A@northamerica can be
resolved using: getent passwd uniq_user_A
But uniq_user_B in domain "europe" can ONLY be resolved using: getent passwd
europe\\unique_user_B
Where I would expect that getent passwd uniq_user_B would also work
(see my configuration file attached below).
Diving into the sssd log files, it seems that when specifying just
"uniq_user_B", the DC's are contacted for the europe domain; which it
can't access since it's not in the kerberos keytab.
What is the relationship between the domains? Are they from the same
forest?
