Hi All,

I'm seeing this kind of error logs in my linux environment: pam_sss(su:session): Request to sssd failed. Connection refused

This error logs shows up constantly, I guess there are some cron jobs are trying to run sudo commands, but the connection request from pam_sss to sssd is refused. 

session     optional      pam_keyinit.so revoke

session     required      pam_limits.so
session     [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid
session     required      pam_unix.so
session     optional      pam_sss.so

Above is the session section from system-auth file, I used "authconfig --enablesssd --enablesssdauth --enablelocauthorize --update" to configure the system files.

1. "service sssd status" is returning running, and I can ssh login local linux users and also ldap users. 

2. I commented our "session optional pam_sss.so" , the error logs still coming out constantly.

Any idea about debugging this problem ? Or is there a known issue about this ?

Thanks,

Aaron
