Issue:
When I use PAM to launch a putty session to RHEL 6.9 PAM SC endpoint using a shared AD account which is bridged in Centrify. All settings for PAM/PAM SC integration have been setup previously.

The putty session hangs and the box is hung for about 5 minutes (no response to any command). /var/adm/loginlog displays:

Jun 18 11:16:34 chidmdev242 seoswd: Communication time out to seosd. Executing seosd
Jun 18 11:18:44 chidmdev242 seoswd: Communication time out to seosd. Executing seosd
Jun 18 11:20:44 chidmdev242 seoswd: Communication time out to seosd. Executing seosd

Jun 18 11:20:44 chidmdev242 seoswd: Communication time out to seosd. Executing seosd

The shared account (svc_strg) can login directly through putty and is enabled with pupm_flags (use_original_identity)

The system-auth file has not been changed by puppet (issue we saw earlier)
ls -l system-auth
lrwxrwxrwx 1 root root 14 May 31 13:50 system-auth -> system-auth-cm
