|
.Bl -tag -width "rpc_gss_svc_integrity"
|
|
.It rpc_gss_svc_default

The default - typically the same as
|
|
.Dv rpc_gss_svc_none .

.It rpc_gss_svc_none
|
|
RPC headers only are integrity protected by a checksum.
|
|
.It rpc_gss_svc_integrity
|
|
RPC headers and data are integrity protected by a checksum.
|
|
.It rpc_gss_svc_privacy
|
|
RPC headers are integrity protected by a checksum and data is encrypted.
|
|
.El

|
|
.It options_req
|
|
Extra security context options to be passed to the underlying GSS-API
|
|

|
|
.It options_ret
|

.Sh RETURN VALUES
|
|
If the security context was created successfully, a pointer to an
|
|
.Vt AUTH
|
|

To use this security context for subsequent RPC calls, set
|
|
.Va clnt->cl_auth
