25             =head1 NAME
26              
27             Config::Parser::ldap - configuration file parser for ldap.conf
28              
29             =head1 SYNOPSIS
30              
31             $cfg = new Config::Parser::ldap($filename);
32              
33             $base = $cfg->get('base');
34              
35              
36             =head1 DESCRIPTION
37              
38             A parser for F and similar files.
39              
40             The syntax of F configuration file is very simple. Each statement
41             occupies one physical line and consists of a keyword and its value separated
42             by one or more space characters. Keywords are case-insensitive. A value
43             starts with the first non-blank character after the keyword, and terminates
44             at the end of the line, or at the last sequence of blanks before the end of
45             the line.
46              
47             Blank lines and lines beginning with a hash mark are ignored.
48              
49             =head1 CONSTRUCTOR
50              
51             =head2 $cfg = new Config::Parser::ldap(%opts);
52              
53             Parses the supplied configuration file and creates a new object for
54             manipulating its settings. Keyword arguments I<%opts> are:
55              
56             =over 4
57              
58             =item filename
59              
60             Name of the file to parse. The file must exist.
61              
62             =item line
63              
64             Optional line where the configuration starts in I<$filename>. It is used
65             to keep track of statement location in the file for correct diagnostics.
66             If not supplied, 1 is assumed.
67              
68             =item fh
69              
70             File handle to read from. If it is not supplied, new handle will be
71             created by using open on the supplied I<$filename>.
72              
73             =item lexicon
74              
75             Dictionary of configuration statements that are allowed in the file. You
76             will most probably not need this parameter. It is listed here for completeness
77             sake. Refer to the L constructor for details.

88             =head1 METHODS
89              
90             All methods for accessing the configuration settings are inherited from
91             L.
92              
93             If you wish to use this class as a base class, please refer to
94             L for implementation details.

96             =head1 EXAMPLE
97              
98             The following simplified example shows how to use this module to connect
99             and bind to a LDAP server.

106              
107             # Connect to server.
108             $ldap = Net::LDAP->new($cf->uri->value);
109
