  • 發行項

The LSAPR_TRUSTED_DOMAIN_INFORMATION_EX structure communicates properties of a trusted domain. The following structure corresponds to the TrustedDomainInformationEx information class. Domain trusts are specified in [MS-ADTS] section 6.1.6.

 typedef struct _LSAPR_TRUSTED_DOMAIN_INFORMATION_EX {
   RPC_UNICODE_STRING Name;
   RPC_UNICODE_STRING FlatName;
   PRPC_SID Sid;
   unsigned long TrustDirection;
   unsigned long TrustType;
   unsigned long TrustAttributes;
 } LSAPR_TRUSTED_DOMAIN_INFORMATION_EX,
  *PLSAPR_TRUSTED_DOMAIN_INFORMATION_EX;

Name: The DNS name of the domain. Maps to the Name field, as specified in section 3.1.1.5.

FlatName: The NetBIOS name of the trusted domain, as specified in [RFC1088]. Maps to the Flat Name field, as specified in section 3.1.1.5.

Sid: The domain SID. Maps to the Security Identifier field, as specified in section 3.1.1.5.

TrustDirection: This field contains bitmapped values that define the properties of the direction of trust between the local domain and the named domain. One or more of the valid flags can be set. If all bits are 0, the trust is said to be disabled.
