Applies to: Centrify DirectControl 5.0.x on Oracle Solaris 11.1 only

Problem:
After Centrify is joined and a user is added to the Zone, an attempt to login results in the following PAM authentication failure:

sshd[6986]: [ID 800047 auth.error] error: PAM: Authentication failed for oracle from host1.domain.com

Cause:
In Oracle Solaris 11.1, the PAM configuration completely changed when compared to the previous release Solaris 11, the changes caused the PAM authentication to fail.

Workaround:
Modify /etc/pam.d/login and add the following 2 lines at the top:

auth sufficient pam_centrifydc.so unix_cred
auth requisite pam_centrifydc.so deny

Modify /etc/pam.d/other and add the following 7 lines at the top:

auth sufficient pam_centrifydc.so unix_cred
auth requisite pam_centrifydc.so deny
account sufficient pam_centrifydc.so
account requisite pam_centrifydc.so deny
session required pam_centrifydc.so
password sufficient pam_centrifydc.so try_first_pass
password requisite pam_centrifydc.so deny

Also, modify /etc/pam.d/passwd and add the following 4 lines at the top:

auth sufficient pam_centrifydc.so try_first_pass
auth requisite pam_centrifydc.so deny
account sufficient pam_centrifydc.so unix_cred
account requisite pam_centrifydc.so deny

Then test again.

Resolution:
This is fixed in Centrify DirectControl 5.1.1
