.Sh SYNOPSIS

|

|
.Sh DESCRIPTION
|
|
Delete a security context.
|
|
.Fn gss_delete_sec_context
|
|
will delete the local data structures associated with the specified
|
|
security context,
|
|
and may generate an output_token,
|
|
which when passed to the peer
|
|
.Fn gss_process_context_token
|
|
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
|
|
specified by
|
|
.Fa context_handle .
|
|
.Pp
|
|
In addition to deleting established security contexts,
|
|
.Fn gss_delete_sec_context
|
|
must also be able to delete "half-built" security contexts resulting
|
|
from an incomplete sequence of
|
|
.Fn gss_init_sec_context
|
|
/
|
|
.Fn gss_accept_sec_context
|
|
calls.
|
|
.Pp
|
|
The
|
|
.Fa output_token
|
|
parameter is retained for compatibility with version 1 of the GSS-API.
|
|
It is recommended that both peer applications invoke
|
|
.Fn gss_delete_sec_context
|
|
passing the value
|
|
.Dv GSS_C_NO_BUFFER
|
|
for the
|
|
.Fa output_token
|
|
parameter,
|
|
indicating that no token is required,
|
|
and that
|
|
.Fn gss_delete_sec_context
|
|
should simply delete local context data structures.
|
|
If the application does pass a valid buffer to
|
|
.Fn gss_delete_sec_context ,
|
|
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.
|
|
.Sh PARAMETERS
|
|
.Bl -tag
|
|
.It minor_status
|
|
Mechanism specific status code.
|
|
.It context_handle
|
|
Context handle identifying context to delete.
|
|
After deleting the context,
|
|
the GSS-API will set this context handle to
|
|
.Dv GSS_C_NO_CONTEXT .
|
|
.It output_token
|
|
Token to be sent to remote application to instruct it to also delete
|
|
the context.
|
|
It is recommended that applications specify
|
|
.Dv GSS_C_NO_BUFFER
|
|
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.
