45.Sh DESCRIPTION
46This function is used to establish a security context between an
47application and a remote peer using the RPSEC_GSS protocol.
48.Sh PARAMETERS
49.Bl -tag -width "options_req"
50.It clnt
51An RPC handle which is connected to the remote peer
52.It principal
53The name of the service principal on the remote peer.
54For instance, a principal such as
55.Qq nfs@server.example.com
56might be used by an application which needs to contact an NFS server
57.It mechanism
58The desired mechanism for this security context.
59The value of mechanism should be the name of one of the security
60mechanisms listed in /etc/gss/mech.
61.It service
62Type of service requested.
63.Bl -tag -width "rpc_gss_svc_integrity"
64.It rpc_gss_svc_default
65The default - typically the same as
66.Dv rpc_gss_svc_none .
67.It rpc_gss_svc_none
68RPC headers only are integrity protected by a checksum.
69.It rpc_gss_svc_integrity
70RPC headers and data are integrity protected by a checksum.
71.It rpc_gss_svc_privacy
72RPC headers are integrity protected by a checksum and data is encrypted.
73.El
74.It qop
75Desired quality of protection or NULL for the default.
76Available values are listed in /etc/gss/qop
77.It options_req
78Extra security context options to be passed to the underlying GSS-API
79mechanism.
80Pass
81.Dv NULL
82to supply default values.
83.It options_ret
84Various values returned by the underlying GSS-API mechanism.
85Pass
86.Dv NULL
87if these values are not required.
88.El
89.Sh RETURN VALUES
90If the security context was created successfully, a pointer to an
91.Vt AUTH
92structure that represents the context is returned.
93To use this security context for subsequent RPC calls, set
94.Va clnt->cl_auth
95to this value.
