r12863: As lha suggested to me a while back, it appears that the
gsskrb5_get_initiator_subkey() routine is bougs. We can indeed use gss_krb5_get_subkey(). This is fortunate, as there was a segfault bug in 'initiator' version. Andrew Bartlett (This used to be commit ec11870ca1f9231dd3eeae792fc3268b31477e11)
