44 * svcauthsw is the bdevsw of server side authentication.
46 * Server side authenticators are called from authenticate by
47 * using the client auth struct flavor field to index into svcauthsw.
48 * The server auth flavors must implement a routine that looks
52 * flavorx_auth(rqst, msg)
53 * register struct svc_req *rqst;
54 * register struct rpc_msg *msg;

77 * The call rpc message, msg has been obtained from the wire. The msg contains
78 * the raw form of credentials and verifiers. authenticate returns AUTH_OK
79 * if the msg is successfully authenticated. If AUTH_OK then the routine also
80 * does the following things:
81 * set rqst->rq_xprt->verf to the appropriate response verifier;
82 * sets rqst->rq_clntcred to the "cooked" form of the credentials.
84 * NB: rqst->rq_xprt->verf must be pre-alloctaed;
85 * its length is set appropriately.
87 * The caller still owns and is responsible for msg->u.cmb.cred and
88 * msg->u.cmb.verf. The authentication system retains ownership of
89 * rqst->rq_clntcred, the cooked credentials.
91 * There is an assumption that any flavour less than AUTH_NONE is
