‏108-Ignore Delegation Failure

Filled under:


Computer/User Node :

Policy Path :
   Administrative Templates\System\Remote Procedure Call

Supported on :
   At least Microsoft Windows Server 2003

Help/Explain Text :
   Directs the RPC Runtime to ignore delegation failures if delegation was asked for. Windows Server 2003 family includes a new delegation model - constrained delegation. In this model the security system does not report that delegation was enabled on a security context when a client connects to a server. Callers of RPC and COM are encouraged to use the RPC_C_QOS_CAPABILITIES_IGNORE_DELEGATE_FAILURE flag, but some applications written for the traditional delegation model may not use this flag and will encounter RPC_S_SEC_PKG_ERROR when connecting to a server that uses constrained delegation. If you disable this setting, do not configure it or set it to Off, the RPC Runtime will generate RPC_S_SEC_PKG_ERROR errors to applications that ask for delegation and connect to servers using constrained delegation. If you configure this setting to On, the RPC Runtime will accept security contexts that do not support delegation as well as security contexts that do support delegation. -- Off directs the RPC Runtime to generate RPC_S_SEC_PKG_ERROR if the client asks for delegation, but the created security context does not support delegation. -- On directs the RPC Runtime to accept security contexts that do not support delegation even if delegation was asked for.
