* @brief Initiate Delegation
* @ingroup globus_gsi_gssapi_extensions_delegation
* @details
* This functions drives the initiating side of the credential
* delegation process. It is expected to be called in tandem with the
* gss_accept_delegation function.
*
* @param minor_status
* The minor status returned by this function. This parameter
* will be 0 upon success.
* @param context_handle
* The security context over which the credential is
* delegated.
* @param cred_handle
* The credential to be delegated. May be GSS_C_NO_CREDENTIAL
* in which case the credential associated with the security
* context is used.
* @param desired_mech
* The desired security mechanism. Currently not used. May be
* GSS_C_NO_OID.
* @param extension_oids
* A set of extension OIDs corresponding to buffers in the
* extension_buffers parameter below. The extensions specified
* will be added to the delegated credential. May be
* GSS_C_NO_BUFFER_SET.
* @param extension_buffers
* A set of extension buffers corresponding to OIDs in the
* extension_oids parameter above. May be
* GSS_C_NO_BUFFER_SET.
* @param input_token
* The token that was produced by a prior call to
* gss_accept_delegation. This parameter will be ignored the
* first time this function is called.
* @param req_flags
* Flags that modify the behavior of the function. Currently
* only GSS_C_GLOBUS_SSL_COMPATIBLE and
* GSS_C_GLOBUS_LIMITED_DELEG_PROXY_FLAG are checked for. The
* GSS_C_GLOBUS_SSL_COMPATIBLE flag results in tokens that
* aren't wrapped and GSS_C_GLOBUS_LIMITED_DELEG_PROXY_FLAG
* causes the delegated proxy to be limited (requires that no
* extensions are specified.
*
* @param time_req
* The requested period of validity (seconds) of the delegated
* credential. Passing a time_req of 0 cause the delegated credential to
* have the same lifetime as the credential that issued it.
* @param output_token
* A token that should be passed to gss_accept_delegation if the
* return value is GSS_S_CONTINUE_NEEDED.
* @retval GSS_S_COMPLETE Success
* @retval GSS_S_CONTINUE_NEEDED This function needs to be called again.
* @retval GSS_S_FAILURE upon failure
