Receiving pam_unix(sshd:session): authentication failures, then pam_sss(sshd:auth): authentication success
Issue
- SSH Login to linux servers shows pam_unix authentication failure for non-local (IdM) users
If an IdM user (sssd) tries to login via ssh first you get pam_unix error then pam_sss success, errors like this are seen in /var/log/secure log :
Oct 22 08:22:12 client1 sshd[3123581]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=client1.example.com user=user22
Oct 22 08:22:13 client1 sshd[3123581]: pam_sss(sshd:auth): authentication success; logname= uid=0 euid=0 tty=ssh ruser= rhost=client1.example.com user=user22
Environment
