4. Examples
This section gives a few examples of search filters written using this notation.
(cn=Babs Jensen)
(!(cn=Tim Howes))
(&(objectClass=Person)(|(sn=Jensen)(cn=Babs J*)))
(o=univ*of*mich*)
(seeAlso=)
The following examples illustrate the use of extensible matching.
(cn:caseExactMatch:=Fred Flintstone)
(cn:=Betty Rubble)
(sn:dn:2.4.6.8.10:=Barney Rubble)
(o:dn:=Ace Industry)
(:1.2.3:=Wilma Flintstone)
(:DN:2.4.6.8.10:=Dino)
The first example shows use of the matching rule "caseExactMatch."
The second example demonstrates use of a MatchingRuleAssertion form without a matchingRule.
The third example illustrates the use of the ":oid" notation to indicate that the matching rule identified by the OID "2.4.6.8.10" should be used when making comparisons, and that the attributes of an entry's distinguished name should be considered part of the entry when evaluating the match (indicated by the use of ":dn").
The fourth example denotes an equality match, except that DN components should be considered part of the entry when doing the match.
The fifth example is a filter that should be applied to any attribute
supporting the matching rule given (since the
The sixth and final example is also a filter that should be applied to any attribute supporting the matching rule given. Attributes supporting the matching rule contained in the DN should also be considered.
The following examples illustrate the use of the escaping mechanism.
(o=Parens R Us \28for all your parenthetical needs\29)
(cn=*\2A*)
(filename=C:\5cMyFile)
(bin=\00\00\00\04)
(sn=Lu\c4\8di\c4\87)
(1.3.6.1.4.1.1466.0=\04\02\48\69)
The first example shows the use of the escaping mechanism to represent parenthesis characters. The second shows how to represent a "*" in an assertion value, preventing it from being interpreted as a substring indicator. The third illustrates the escaping of the backslash character.
The fourth example shows a filter searching for the four-octet value 00 00 00 04 (hex), illustrating the use of the escaping mechanism to represent arbitrary data, including NUL characters.
The fifth example illustrates the use of the escaping mechanism to
represent various non-ASCII UTF-8 characters. Specifically, there
are 5 characters in the
The sixth and final example demonstrates assertion of a BER-encoded value.
