I have my CentOS 6 system configured to use sssd with ldap provider. I am able to login and use sudo, however /var/log/secure always reports authentication failure:
Sep 18 07:09:52 serverA sudo: pam_unix(sudo:auth): authentication failure; logname=exampleuser uid=10000 euid=0 tty=/dev/pts/1 ruser=exampleuser rhost= user=exampleuser Sep 18 07:09:52 serverA sudo: pam_sss(sudo:auth): authentication success; logname=exampleuser uid=10000 euid=0 tty=/dev/pts/1 ruser=exampleuser rhost= user=exampleuser
This is causing false positives in my SIEM. I think the issue is with pam. I configured it using authconfig. Is there a way to configure pam to not check /etc/passwd for ldap users (say users above X uid) or another solution to this problem?
