A filter specifies the conditions that must be met for a record to be included in the recordset (or collection) that results from a query. An LDAP filter has one or more clauses, each enclosed in parentheses. Each clause evaluates to either True or False. An LDAP syntax filter clause is in the following form:
(
The
Operator | Meaning |
= | Equality |
>= | Greater than or equal to (lexicographical) |
<= | Less than or equal to (lexicographical) |
Note that the operators "<" and ">" are not supported. Another operator, ~= (which means approximately equal to) is supported, but no case has been found where this is useful in Active Directory. The
(cn=Jim Smith)
This filters on all objects where the value of the cn attribute (the common name of the object) is equal to the string "Jim Smith" (not case sensitive). Filter clauses can be combined using the following operators:
Operator | Meaning |
& | AND, all conditions must be met |
| | OR, any of the conditions must be met |
! | NOT, the clause must evaluate to False |
For example, the following specifies that either the cn attribute must be "Jim Smith", or the givenName attribute must be "Jim" and the sn attribute must be "Smith":
(|(cn=Jim Smith)(&(givenName=Jim)(sn=Smith)))
Conditions can be nested with parentheses, but make sure the parentheses match up.

The LDAP filter specification assigns special meaning to the following characters:
* ( ) \ NUL
The NUL character is ASCII 00. In LDAP filters these 5 characters should be escaped with the backslash escape character, followed by the two character ASCII hexadecimal representation of the character. The following table documents this:
Character | Hex Representation |
* | \2A |
( | \28 |
) | \29 |
\ | \5C |
Nul | \00 |
For example, to find all objects where the common name is "James Jim*) Smith", the LDAP filter would be:
(cn=James Jim\2A\29 Smith)
Actually, the parentheses only need to be escaped if they are unmatched, as above. If instead the common name were"James (Jim) Smith", nothing would need to be escaped. However, any characters, including non-display and foreign characters, can be escaped in a similar manner in an LDAP filter. For example, here are a few foreign characters:
Character | Hex Representation |
á | \E1 |
é | \E9 |
í | \ED |
ó | \F3 |
ú | \FA |
ñ | \F1 |

When your filter clause includes the objectCategory attribute, LDAP does some magic to convert the values for your convenience. The objectCategory attribute is a DN attribute. A typical value for an object in Active Directory might be"cn=person,cn=Schema,cn=Configuration,dc=MyDomain,dc=com". You can use a filter clause similar to the following:
(objectCategory=cn=person,cn=Schema,cn=Configuration,dc=MyDomain,dc=com)
However, Active Directory allows you to instead use the following shortcut:
(objectCategory=person)
The following table documents the result of various combinations of clauses specifying values for objectCategory and objectClass:
objectCategory | objectClass | Result |
person | user | user objects |
person | user and contact objects | |
person | contact | contact objects |
user | user and computer objects | |
computer | computer objects | |
user | user and contact objects | |
contact | contact objects | |
computer | computer objects | |
person | user, computer, and contact objects | |
contact | user and contact objects | |
group | group objects | |
group | group objects | |
person | organizationalPerson | user and contact objects |
organizationalPerson | user, computer, and contact objects | |
organizationalPerson | user and contact objects |
Use the filter that makes your intent most clear. Also, if you have a choice between using objectCategory and objectClass, it is recommended that you use objectCategory. That is because objectCategory is both single valued and indexed, while objectClass is multi-valued and not indexed (except on Windows Server 2008 and above). A query using a filter with objectCategory will be more efficient than a similar filter with objectClass. Windows Server 2008 domain controllers (and above) have a special behavior that indexes the objectClass attribute. You can take advantage of this if all of your domain controllers are Windows Server 2008, or if you specify a Windows Server 2008 domain controller in your query.
