=head1 Kamailio::LDAPUtils::LDAPConf
Kamailio::LDAPUtils::LDAPConf - Read openldap config from standard config files.
use Kamailio::LDAPUtils::LDAPConf;
my $conf = new Kamailio::LDAPUtils::LDAPConf();
This module may be used to retrieve the global LDAP configuration as
used by other LDAP software, such as C<nsswitch.ldap> and C<pam-ldap>.
The configuration is usualy stored in C</etc/openldap/ldap.conf>
When used from an account with sufficient privilegs (e.g. root), the
ldap manager passwort is also retrieved.
=cut
package Kamailio::LDAPUtils::LDAPConf;
my $def_ldap_path = "/etc/openldap" ;
my $def_conf = "ldap.conf";
my $def_secret = "ldap.secret";
=head2 Constructor new()
Returns a new, initialized C<Kamailio::LDAPUtils::LDAPConf> object.
=cut
sub new {
my $class = shift;
my $self = _init( $def_ldap_path . "/" . $def_conf ,
$def_ldap_path . "/" . $def_secret);
if( ! $self ) { return undef; } ## can happen during customizing
bless $self , $class;
return $self;
}
sub _init {
my $conf_file = shift;
my $secret_file = shift;
my $result = {};
if( open(LDAPCONF,"<$conf_file") ) {
while(<LDAPCONF>) {
chomp;
s/#.*$//;
if( m/^\s*$/ ) { next; }
my ($var,$val) = split(" ",$_,2);
$result->{lc($var)} = $val;
}
close(LDAPCONF);
} else {
return undef;
}
if( -r $secret_file ) {
if( open(SECRET,"<$secret_file") ) {
my $secret = <SECRET>;
chomp $secret;
$result->{'rootbindpw'} = $secret;
close(SECRET);
}
}
return $result;
}
=head2 Method base()
Returns the servers base-dn to use when doing queries.
=cut
sub base { return $_[0]->{'base'}; }
=head2 Method host()
Returns the ldap host to contact.
=cut
sub host { return $_[0]->{'host'}; }
=head2 Method port()
Returns the ldap servers port.
=cut
sub port { return $_[0]->{'port'}; }
=head2 Method uri()
Returns an uri to contact the ldap server. When there is no ldap_uri in
the configuration file, an C<ldap:> uri is constucted from host and port.
=cut
sub uri {
my $self = shift;
if( $self->{'ldap_uri'} ) { return $self->{'ldap_uri'}; }
return "ldap://" . $self->host . ":" . $self->port ;
}
=head2 Method rootbindpw()
Returns the ldap "root" password.
Note that the C<rootbindpw> is only available when the current account has
sufficient privilegs to access C</etc/openldap/ldap.secret>.
=cut
sub rootbindpw { return $_[0]->{'rootbindpw'}; }
=head2 Method rootbinddn()
Returns the DN to use for "root"-access to the ldap server.
=cut
sub rootbinddn { return $_[0]->{'rootbinddn'}; }
=head2 Method binddn()
Returns the DN to use for authentication to the ldap server. When no
bind dn has been specified in the configuration file, returns the
C<rootbinddn>.
=cut
sub binddn {
my $self = shift;
if( $self->{'binddn'} ) { return $self->{'binddn'}; }
return $self->rootbinddn;
}
=head2 Method bindpw()
Returns the password to use for authentication to the ldap server. When no
bind password has been specified, returns the C<rootbindpw> if any.
=cut
sub bindpw {
my $self = shift;
if( $self->{'bindpw'} ) { return $self->{'bindpw'}; }
return $self->rootbindpw;
