Hi Folks, I'm been attempting to setup a new server running a standard KDC (V5) and AFS (and incidentally LDAP). Everything configured OK (didn't get as far as creating volumes other root.afs and root.cell). I'm seeing problems logging in as Kerberos/LDAP defined user. Login was fine prior to the AFS setup, post AFS setup generates a kernel "crash" which I'm assuming is related to pam_krb5 attempting to get AFS tokens (but am not sure). I'm seeing this with both the Fedora Core 8 RPMs from www.openafs.org and using a locally 1.5.27 build. Excluding timestamps and hostname info, the 1.4.5/var/log/messages entries are
