I've setup an alternative authentication system (Centrify). That works great with AD. But now, for some reason I can't login with local users (including root). I'm getting a krb5 error: Nov 29 10:06:54 library gdm[32097]: pam_krb5[32097]: authentication fails for 'lois' ( <a href="mailto:lois@UCASTUDENT.NET" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">lois@UCASTUDENT.NET</a>): User not known to the underlying authentication module (Client not found in Kerberos database) Nov 29 10:06:56 library gdm[32097]: Couldn't authenticate user Nov 29 10:07:04 library gdm[32097]: pam_krb5[32097]: authentication fails for 'lois' (<a href="mailto:lois@UCASTUDENT.NET" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">lois@UCASTUDENT.NET </a>): User not known to the underlying authentication module (Client not found in Kerberos database) Nov 29 10:07:07 library gdm[32097]: Couldn't authenticate user I'm thinking its because of some of the tinkering I've done with the system-auth when setting up the previous ldap integration. Does this sound right. Can someone send me a sample of what the system-auth sould look like on a default install? I can't post mine as the only admin type access I have is with linux rescue. -- Mel Wade "The real problem is not whether machines think but whether men do." - BF Skinner <a href="http://www.melwade.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.melwade.com </a>
