For the error in the krb5_child.log
(Tue Mar 15 04:35:51 2016) [[sssd[krb5_child[13708]]]]
[sss_child_krb5_trace_cb] (0x4000): [13708] 1458016551.87210: Received
error from KDC: -1765328359/Additional pre-authentication required

I deleted the sssd cache as well as the /tmp/krb5* and restarted sssd ,
still the issue persists.

Another error that I see is in /var/log/secure

Mar 14 21:35:51 ip-1-1-1-1 sshd[13705]: pam_unix(sshd:auth): authentication
failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=127.0.0.1
user=q-tempuser
Mar 14 21:35:51 ip-1-1-1-1 sshd[13705]: pam_sss(sshd:auth): authentication
failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=127.0.0.1
user=q-tempuser
Mar 14 21:35:51 ip-1-1-1-1 sshd[13705]: pam_sss(sshd:auth): received for
user q-tempuser: 4 (System error)

I have "UsePAM yes" and "GSSAPIAuthentication yes" in sshd_config.

so not sure whats causing this..

I tried uninstalling and installing back the client as well but did not
help..

Anything else that I might be missing out..

Thanks,
Rakesh
