[Freeipa-users] Cannot login with GSSAPI to IPA client

Tue Jun 16 23:32:31 UTC 2015

I have 2 CentOS 6 clients both running FreeIPA client 3.0.0-42 and sssd
1.11.6-30.  The server is CentOS 7 / IPA 4.1.3

When I try to log in using MIT kerberos and a valid ticket it works on one
client, and fails on the other.  I have compared the /etc/krb5.conf,
/etc/sssd/sssd.conf and /etc/openldap/ldap.conf files on both clients and
they are identical (other than the hostnames).  I can't seem to find any
other difference between the clients.

Password authentication works on both machines.

Here is the dub log of the failed login machine (sshd)

I think the relevant line is the very last one where it postpones the
login for some reason

Postponed gssapi-with-mic for username from 10.5.5.57 port 15076 ssh2
