NAME

Net::LDAP::Filter - representation of LDAP filters

SYNOPSIS

  use Net::LDAP::Filter;

  $filter = Net::LDAP::Filter->new( $filter_str );

DESCRIPTION

The Net::LDAP::Filter object lets you directly manipulate LDAP filters without worrying about the string representation and all the associated escaping mechanisms.

CONSTRUCTOR

new ( FILTER )

Create a new object and parse FILTER.

METHODS

parse ( FILTER )

Parse FILTER. The next call to ber will return this filter encoded.

as_string

Return the filter in text form.

Print the text representation of the filter to FH, or the currently selected output handle if FH is not given.

FILTER SYNTAX

Below is the syntax for a filter given in RFC-2254 http://www.ietf.org/rfc/rfc2254.txt

 filter       = "(" filtercomp ")"
 filtercomp   = and / or / not / item
 and          = "&" filterlist
 or           = "|" filterlist
 not          = "!" filter
 filterlist   = 1*filter
 item         = simple / present / substring / extensible
 simple       = attr filtertype value
 filtertype   = equal / approx / greater / less
 equal        = "="
 approx       = "~="
 greater      = ">="
 less         = "<="
 extensible   = attr [":dn"] [":" matchingrule] ":=" value
                / [":dn"] ":" matchingrule ":=" value
 present      = attr "=*"
 substring    = attr "=" [initial] any [final]
 initial      = value
 any          = "*" *(value "*")
 final        = value
 attr         = AttributeDescription from Section 4.1.5 of RFC-2251
 matchingrule = MatchingRuleId from Section 4.1.9 of RFC-2251
 value        = AttributeValue from Section 4.1.6 of RFC-2251
