.Sh DESCRIPTION
|
|
Provides a way to pass an asynchronous token to the security service.
|
|
Most context-level tokens are emitted and processed synchronously by
|
|
.Fn gss_init_sec_context
|
|
and
|
|
.Fn gss_accept_sec_context ,
|
|
and the application is informed as to whether further tokens are
|
|
expected by the
|
|
.Dv GSS_C_CONTINUE_NEEDED
|
|
major status bit.
|
|
Occasionally,
|
|
a mechanism may need to emit a context-level token at a point when the
|
|
peer entity is not expecting a token.
|
|
For example,
|
|
the initiator's final call to
|
|
.Fn gss_init_sec_context
|
|
may emit a token and return a status of
|
|
.Dv GSS_S_COMPLETE ,
|
|
but the acceptor's call to
|
|
.Fn gss_accept_sec_context
|
|
may fail.
|
|
The acceptor's mechanism may wish to send a token containing an error
|
|
indication to the initiator,
|
|
but the initiator is not expecting a token at this point,
|
|
believing that the context is fully established.
|
|
.Fn gss_process_context_token
|
|
provides a way to pass such a token to the mechanism at any time.
