In fact support for Kerberos 5 in distribution sources of OpenSSH is limited only to talk to KDC and get the Kerberos ticket from it. If you want to use a kerberos ticket received from the KDC with ``kinit'' command, you can't, because OpenSSH doesn't support ticket forwarding in it's original distribution. To use a ticket forwarding you have to apply a Simon Wilkinson's GSSAPI patches for OpenSSH.
Aditionally to have both Kerberos and Password anthentication in OpenSSH you have to set sshd_config's option ``KerberosOrLocalPasswd'' to ``yes''.
good luck
