ldapfilter.conf - configuration file for LDAP filtering routines




The ldapfilter.conf file contains information used by the LDAP filtering

Blank lines and lines that begin with a hash character (#) are treated as
comments and ignored. The configuration information consists of lines
that contain one to five tokens. Tokens are separated by white space, and
double quotes can be used to include white space inside a token.

The file consists of a sequence of one or more filter sets. A filter set
begins with a line containing a single token called a tag.

The filter set consists of a sequence of one or more filter lists. The
first line in a filter list must contain four or five tokens: the value
pattern, the delimiter list, a filtertemplate, a match description, and
an optional search scope. The value pattern is a regular expression that
is matched against the value passed to the LDAP library call to select
the filter list.

The delimiter list is a list of the characters (in the form of a single
string) that can be used to break the value into distinct words.

The filter template is used to construct an LDAP filter (see description

The match description is returned to the caller along with a filter as a
piece of text that can be used to describe the sort of LDAP search that
took place. It should correctly compete both of the following phrases:
"One match description match was found for ..." and "Three match
description matches were found for...."

The search scope is optional, and should be one of base, onelevel, or
subtree. If search scope is not provided, the default is subtree.

The remaining lines of the filter list should contain two or three
tokens, a filter template, a match description and an optional search

The filter template is similar in concept to a printf(3C) style format
string. Everything is taken literally except for the character sequences:

Substitute the entire value string in place of the %v.

Substitute the last word in this field.

Substitute word N in this field (where N is a single digit 1-9).
Words are numbered from left to right within the value starting
at 1.

Substitute the indicated sequence of words where M and N are
both single digits 1-9.

Substitute word N through the last word in value where N is
again a single digit 1-9.


Example 1: An LDAP Filter Configuration File

The following LDAP filter configuration file contains two filter sets,
example1 and example2 onelevel, each of which contains four filter lists.

# ldap filter file
"=" " " "%v" "arbitrary filter"
"[0-9][0-9-]*" " " "(telephoneNumber=*%v)" "phone number"

"@" " " "(mail=%v)" "email address"

"^.[. _].*" ". _" "(cn=%v1* %v2-)" "first initial"

".*[. _].$" ". _" "(cn=%v1-*)" "last initial"

"[. _]" ". _" "(|(sn=%v1-)(cn=%v1-))" "exact"
"(|(sn~=%v1-)(cn~=%v1-))" "approximate"

".*" ". " "(|(cn=%v1)(sn=%v1)(uid=%v1))" "exact"
"(|(cn~=%v1)(sn~=%v1))" "approximate"

"example2 onelevel"
"^..$" " " "(|(o=%v)(c=%v)(l=%v)(co=%v))" "exact" "onelevel"
"(|(o~=%v)(c~=%v)(l~=%v)(co~=%v))" "approximate"

" " " " "(|(o=%v)(l=%v)(co=%v)" "exact" "onelevel"
"(|(o~=%v)(l~=%v)(co~=%v)" "approximate" "onelevel"

"." " " "(associatedDomain=%v)" "exact" "onelevel"

".*" " " "(|(o=%v)(l=%v)(co=%v)" "exact" "onelevel"
"(|(o~=%v)(l~=%v)(co~=%v)" "approximate" "onelevel"
