[CentOS] Kerberos integration in directory server
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

While our configurations are different I'm sure you're trying for kerberized logins (System authenticates against Kerberos and pulls account information from LDAP). If so here are some items you may want to verify you have included in your system-auth config file. Auth sufficient pam_krb5.so use_first_pass Auth sufficient pam_unix.so nullok try_first_pass Account sufficient pam_ldap.so Account required pam_unix.so Password sufficient pam_krb5.so Password sufficient pam_unix.so sha512 shadow nullok try_first_pass use_authok Session optional pam_keyinit.so revoke Session optional pam_krb5.so Dan

Is it possible for such a user to access a server that only has ldap for authentication and checks against the LDAP-Server ? About testing : How can I check if the information is pulled out of ldap ? Thanks in advance :) Peter
