56 * The call rpc message, msg has been obtained from the wire. The msg contains
57 * the raw form of credentials and verifiers. authenticate returns AUTH_OK
58 * if the msg is successfully authenticated. If AUTH_OK then the routine also
59 * does the following things:
60 * set rqst->rq_xprt->verf to the appropriate response verifier;
61 * sets rqst->rq_client_cred to the "cooked" form of the credentials.
63 * NB: rqst->rq_cxprt->verf must be pre-alloctaed;
64 * its length is set appropriately.
66 * The caller still owns and is responsible for msg->u.cmb.cred and
67 * msg->u.cmb.verf. The authentication system retains ownership of
68 * rqst->rq_client_cred, the cooked credentials.
70 * There is an assumption that any flavour less than AUTH_NULL is
