Hi, Got some issues regarding Kerberos and Directory Server and hope someone can help me out. Used these for the configiruation : http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-kerberos.html http://www.redhat.com/docs/manuals/dir-server/8.1/install/index.html Server : CentOS 5.4 with Kerberos and Directory Server installed Client : CentOS 5.4 I use putty to connect to the client, which authenticates against the server. Using Kerberos or LDAP worked perfectly (using system-config-authentication on the client for configuration) The only thing that doesn't seem to work is the kerberized version of the login via LDAP on the directory Server. Shouldn't I get a Kerberos ticket for that ? If I activate kerberos AND ldap in system-config-authentication it fails : Jan 25 13:24:59 monarch sshd[3947]: pam_unix(sshd:auth): check pass; user unknown Jan 25 13:24:59 monarch sshd[3947]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.0.1 Jan 25 13:24:59 monarch sshd[3947]: pam_succeed_if(sshd:auth): error retrieving information about user testuser Jan 25 13:25:01 monarch sshd[3947]: Failed password for invalid user testuser from 192.168.0.1 port 1142 ssh2 I followed the instructions here : http://directory.fedoraproject.org/wiki/Howto:Kerberos Maybe I just didn't get it ;) Thanks in advance, Peter
