SUMMARY

To achieve the best performance when querying against the Active Directory, you should query indexed attributes. Indexed attributes are configured with the searchFlags bit set of 0x00000001.

To enumerate all indexed attributes, bind to the schema container and use the following LDAP filter: 
(&(objectCategory=attributeSchema)(searchFlags:1.2.840.113556.1.4.803:=1))

MORE INFORMATION

To use the Ldp.exe program to query the active directory enumerating attributes that are indexed for quick searches:
  1. Start the Ldp.exe program, and then increase the text buffer size to 9999.
  2. Bind to a Windows 2000-based domain, and then determine the schema's distinguished name by observing the output of LDP 
    schemaNamingContext: CN=Schema,CN=Configuration,DC=domainName,DC=com
  3. On the Browse menu, click Search, and then type the schemNamingContext value into the Base DN box.

    (&(objectCategory=attributeSchema)(searchFlags:1.2.840.113556.1.4.803:=1))
  5. Click Subtree for the Scope, and then click Options.
  6. Enter the attributes you want to be returned:
