which when passed to the peer
will instruct it to do likewise.
If no token is required by the mechanism,
the GSS-API should set the length field of the output_token (if
provided) to zero.
No further security services may be obtained using the context
In addition to deleting established security contexts,

It is recommended that both peer applications invoke

If the application does pass a valid buffer to
mechanisms are encouraged to return a zero-length token,
indicating that no peer action is necessary,
and that no token should be transferred by the application.

After deleting the context,

It is recommended that applications specify
for this parameter,
requesting local deletion only.
If a buffer parameter is provided by the application,
the mechanism may return a token in it;
mechanisms that implement only local deletion should set the length
field of this token to zero to indicate to the application that no
token is to be sent to the peer.
