Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

My system is CentOS 6.3, openldap is configured well, PAM authorization works fine.

But after turning pam_check_host_attr to yes, all LDAP-auths fail with message "Access denied for this host".

  1. hostname on the server returns correct value, the same value is listed in user's profile.
  2. "pam_check_host_attr no" works fine and allows everyone with correct uid/password
  3. a piece of /var/log/secure:

    Sep 26 05:33:01 ldap sshd[1588]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=my-host user=my-username

    Sep 26 05:33:01 ldap sshd[1588]: Failed password for my-username from 77.AA.BB.CC port 58528 ssh2

    Sep 26 05:33:01 ldap sshd[1589]: fatal: Access denied for user my-username by PAM account configuration

  4. Another two servers (CentOS 5.7 Debian) authorizes on this LDAP server correctly. Even with pam_check_host_attr yes!

  5. I didn't edit /etc/security/access.conf, it is empty, only default comments.

I don't know what to do! How to fix this?

what does the directory server log show for this condition? – Terry Gardner Sep 27 '12 at 16:58
