 ticket: 7051
 subject: krb5_server_decrypt_ticket_keytab wrongly succeeds

 If krb5_server_decrypt_ticket_keytab doesn't find a key of the
 appropriate enctype in an iterable keytab, it returns 0 (without
 decrypting the ticket) due to a misplaced initialization of retval.
 This bug causes kinit -k to claim "keytab entry valid" when it
 shouldn't.  Reported by mark@mproehl.net.
