3.1.4.4.7 LsarQueryDomainInformationPolicy (Opnum 53)

  • Article

The LsarQueryDomainInformationPolicy method is invoked to retrieve policy settings in addition to those exposed through LsarQueryInformationPolicy and LsarSetInformationPolicy2. Despite the term "Domain" in the name of the method, processing of this message occurs with local data, and furthermore, there is no requirement that this data have any relationship with the LSA information in the domain to which the machine is joined.

 NTSTATUS LsarQueryDomainInformationPolicy(
   [in] LSAPR_HANDLE PolicyHandle,
   [in] POLICY_DOMAIN_INFORMATION_CLASS InformationClass,
   [out, switch_is(InformationClass)] 
     PLSAPR_POLICY_DOMAIN_INFORMATION* PolicyDomainInformation
 );

PolicyHandle: An RPC context handle obtained from either LsarOpenPolicy or LsarOpenPolicy2.

InformationClass: A parameter that specifies what type of information the caller is requesting.

PolicyDomainInformation: A parameter that references policy information structure on return.

Return Values: The following is a summary of the return values that an implementation MUST return, as specified by the message processing that follows.

Description

0x00000000

STATUS_SUCCESS

STATUS_INVALID_HANDLE

PolicyHandle is not a valid handle.

Processing:

If the InformationClass parameter is PolicyDomainEfsInformation, and the responder does not support Encrypting File System (EFS) Policy Information as specified in section 3.1.1.1, the request MUST fail with STATUS_OBJECT_NAME_NOT_FOUND.

If the InformationClass parameter is PolicyDomainQualityOfServiceInformation, and the responder implementation does not support Quality Of Service Information as specified in section 3.1.1.1, the request MUST fail with STATUS_INVALID_PARAMETER.

If PolicyHandle is not a valid context handle or PolicyHandle.HandleType does not equal "Policy", the server MUST return STATUS_INVALID_HANDLE.

The server MUST verify that PolicyHandle grants access as specified in section 3.1.4.2.2. The following table specifies the RequiredAccess value to use in this access check for each InformationClass value.

The InformationClass parameter can take on any value in the POLICY_DOMAIN_INFORMATION_CLASS enumeration range. For all values outside this range, the server MUST return the STATUS_INVALID_PARAMETER error code.

PolicyDomainInformation is an output parameter. The server MUST fill it with the information requested by the client, based on the value of the InformationClass parameter and the abstract data model specified in section 3.1.1.1. If the information has not been set before, the request MUST fail with STATUS_OBJECT_NAME_NOT_FOUND.
