47.Sh DESCRIPTION
48This function is used to establish a security context between an
49application and a remote peer using the RPSEC_GSS protocol.
50.Sh PARAMETERS
51.Bl -tag -width "options_req"
52.It clnt
53An RPC handle which is connected to the remote peer
54.It principal
55The name of the service principal on the remote peer.
56For instance, a principal such as
57.Qq nfs@server.example.com
58might be used by an application which needs to contact an NFS server
59.It mechanism
60The desired mechanism for this security context.
61The value of mechanism should be the name of one of the security
62mechanisms listed in /etc/gss/mech.
63.It service
64Type of service requested.
65.Bl -tag -width "rpc_gss_svc_integrity"
66.It rpc_gss_svc_default
67The default - typically the same as
68.Dv rpc_gss_svc_none .
69.It rpc_gss_svc_none
70RPC headers only are integrity protected by a checksum.
71.It rpc_gss_svc_integrity
72RPC headers and data are integrity protected by a checksum.
73.It rpc_gss_svc_privacy
74RPC headers are integrity protected by a checksum and data is encrypted.
75.El
76.It qop
77Desired quality of protection or NULL for the default.
78Available values are listed in /etc/gss/qop
79.It options_req
80Extra security context options to be passed to the underlying GSS-API
81mechanism.
82Pass
83.Dv NULL
84to supply default values.
85.It options_ret
86Various values returned by the underlying GSS-API mechanism.
87Pass
88.Dv NULL
89if these values are not required.
90.El
91.Sh RETURN VALUES
92If the security context was created successfully, a pointer to an
93.Vt AUTH
94structure that represents the context is returned.
95To use this security context for subsequent RPC calls, set
96.Va clnt->cl_auth
97to this value.
