On past versions of redhat and Fedora Core I was able to set up kerberos
authentication with pam without any problem.
On Fedora Core 3 and now 4 I can not get it to work. I set everything
up as before and run kinit <user> and that works. If I do a tcp dump I
can see the port 88 communication occuring.
If I use pam and a service like sshd, I get the error: "sshd[23379]:
Failed password for <user>". A tcpdump reveals no port 88 traffic. It
looks like the pam_krb5.so module is being skipped in the pam stack.
Here are my pam configs:
/etc/pam.d/sshd
