    • Increment the value of the CachedLDAPConnection.RefCount ADM element attribute by 1.

    • Set rADConnection to the value of CachedLDAPConnection.Handle, and set rStatus to DirectoryOperationResult.Success.

    • Take no further action.

  • Let DirectoryServerConnection be a variable of type ADCONNECTION_HANDLE.

  • Perform the Initializing an ADConnection ([MS-ADTS] section 7.6.1.1) task, specifying the following parameters:

    • TaskInputTargetName = NULL

    • TaskInputPortNumber = 389

  • Perform the Setting an LDAP Option on an ADConnection ([MS-ADTS] section 7.6.1.2) task, specifying the following parameters:

    • TaskInputADConnection = DirectoryServerConnection

  • If the TaskReturnStatus result is not success, as specified in [RFC2251] section 4.1.10, rStatus MUST be set to DirectoryOperationResult.GenericError, and processing MUST end.

  • rADConnection MUST be set to DirectoryServerConnection, and rStatus MUST be set to DirectoryOperationResult.Success.
