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 ( [ FH ] )

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
