2.234 Attribute searchFlags

This attribute specifies whether an attribute is indexed, among other things. It is optional and contains the following bitwise flags (further defined in [MS-ADTS] section 2.2.9):

  • fATTINDEX: *


  • fANR: Add this attribute to the ambiguous name resolution (ANR) set. If set, then fATTINDEX has to be set. See [MS-ADTS] for ANR search.

  • fPRESERVEONDELETE: Preserve this attribute on logical deletion. This flag is ignored on link attributes.

  • fCOPY: Interpreted by LDAP clients, not by the server. If set, the attribute is copied on object copy.



  • fCONFIDENTIAL: This attribute is confidential; special access check is needed. For more information, see [MS-ADTS] section


  • fRODCFilteredAttribute: If set, this attribute is in the RODC filtered attribute set.

The searchFlags marked * have an implementation-dependent interpretation defined by Windows. They can be ignored by other implementations, but cannot be used in a conflicting way that would affect the performance of Windows DCs.
