Return value/code

0xC0000401

STATUS_PER_USER_TRUST_QUOTA_EXCEEDED

The caller's quota for maximum number of TDOs that can be created by control access right Create-Inbound-Trust is exceeded.

0xC0000402

STATUS_ALL_USER_TRUST_QUOTA_EXCEEDED

The combined users' quota for maximum number of TDOs that can be created by control access right Create-Inbound-Trust is exceeded.

Processing:

If Active Directory is not running on this machine, the server MUST return STATUS_DIRECTORY_SERVICE_REQUIRED.<86> If the server is a read-only domain controller, it MUST return an error.<87>

If the caller is not a member of the Domain Admins group, the server MUST return STATUS_ACCESS_DENIED for policy handle access checking.

If the TDO creation failed due to the caller not having standard access rights to create the TDO, then the server MUST check the caller's control access right (defined in [MS-ADTS] section 5.1.3.2.1). The TDO creation by control access right is allowed if:

  • The trust is an inbound-only forest trust. The server MUST return STATUS_ACCESS_DENIED if the trust to be created is not an inbound-only forest trust.

  • The caller has the control access right to create an inbound trust on the domain object.

  • The caller's quota for trust object creations has not been exceeded. If the number of TDOs that have been created by the caller through control access right Create-Inbound-Trust exceeds the value in the msDS-PerUserTrustQuota attribute of the domain NC root object, then the server MUST return STATUS_PER_USER_TRUST_QUOTA_EXCEEDED. For the syntax of the msDS-PerUserTrustQuota attribute, refer to [MS-ADA2] section 2.410.

  • The combined users' quota for trust object creations has not been exceeded. If the number of TDOs that have been created through control access right Create-Inbound-Trust exceeds the value in the msDS-AllUsersTrustQuota attribute of the domain NC root object (defined in [MS-ADTS] section 6.1.1.1.4), then the server MUST return STATUS_ALL_USER_TRUST_QUOTA_EXCEEDED. For the syntax of the msDS-AllUsersTrustQuota attribute, refer to [MS-ADA2] section 2.212.

This message takes five arguments:

PolicyHandle: An open handle to the policy object. If the handle is not a valid context handle to the policy object or PolicyHandle.HandleType does not equal "Policy", the server MUST return STATUS_INVALID_HANDLE. PolicyHandle.GrantedAccess MUST NOT be considered for this call because the access check MUST happen on the TDO.

TrustedDomainInformation: A structure containing most components of a TDO makeup. The data provided in this parameter MUST be checked for validity in accordance with rules for TDO consistency specified in "Trust Objects" in [MS-ADTS] section 6.1.6. The server MUST reject invalid input with STATUS_INVALID_PARAMETER. The server MUST return STATUS_INVALID_DOMAIN_STATE in the following cases:

  • The TrustAttributes TRUST_ATTRIBUTE_FOREST_TRANSITIVE flag is set and the forestFunctionality specified in [MS-ADTS] section 3.1.1.3.2.27 is DS_BEHAVIOR_WIN2003 or higher.

  • The TrustAttributes TRUST_ATTRIBUTE_FOREST_TRANSITIVE flag is set and the DnsForestName and DnsDomainName fields in DNS Domain Information (see section 3.1.1.1) do not contain the same value.

  • The TrustAttributes TRUST_ATTRIBUTE_CROSS_ORGANIZATION flag is set and the forestFunctionality specified in [MS-ADTS] section 3.1.1.3.2.27 is DS_BEHAVIOR_WIN2003 or higher.

If one or more properties in TrustedDomainInformation points to the current domain (such as the domain that the server is a part of), the server MUST return STATUS_CURRENT_DOMAIN_NOT_ALLOWED. If there is another domain that claims the same properties, the server MUST return STATUS_OBJECT_NAME_COLLISION. Each field in this structure maps to a field in the TDO model, as specified in section 3.1.1.5. If the operation succeeds, the server MUST update its database with a new TDO field populated from this input parameter.

AuthenticationInformation: A structure containing authentication information for the trusted domain. The server first MUST decrypt this data structure using an algorithm (as specified in section 5.1.1) with the key being the session key negotiated by the transport. The server then MUST unmarshal the data inside this structure and then store it into a structure whose format is specified in section 2.2.7.11. This structure MUST then be stored on Trust Incoming and Outgoing Password properties.

DesiredAccess: A bitmask containing a set of access rights that the caller attempts to obtain from the TDO, which is access-checked as specified in section 3.1.4.2.1. Whatever the set of access rights requested by the caller, the server MUST also set the TRUSTED_SET_AUTH bit inside DesiredAccess before performing the security descriptor check. There is no method-specific portion of the check.

The valid trusted-domain-rights bits are specified in section 2.2.1.1.5, and the security descriptor is specified in section 3.1.1.5.

TrustedDomainHandle:  If the request is successful, this parameter is used to return a handle (section 3.1.1.7) to the newly created TDO with its fields initialized as follows:

  • LsaContextHandle.HandleType = "Trusted Domain"

  • LsaContextHandle.Object = the TDO

  • LsaContextHandle.GrantedAccess = as specified in section 3.1.4.2.1

New TDOs are always created without forest trust information. The ForestTrustInfo and ForestTrustLength fields of the TDO are thus set to NULL and 0, respectively.

If the trust being created is inbound or bidirectional as defined in the TrustDirection field of the TrustedDomainInformation parameter, then the server MUST also update its database with a new interdomain trust account populated as specified in [MS-ADTS] section 6.1.6.8.
