Apple Open Directory

my $ldap = Authen::Simple::LDAP->new( host => '', basedn => 'cn=users,dc=company,dc=com', filter => '(&(objectClass=inetOrgPerson)(objectClass=posixAccount)(uid=%s))' );

Microsoft Active Directory

my $ldap = Authen::Simple::LDAP->new( host => '', binddn => '[email protected]', bindpw => 'secret', basedn => 'cn=users,dc=company,dc=com', filter => '(&(objectClass=organizationalPerson)(objectClass=user)(sAMAccountName=%s))' );

Active Directory by default does not allow anonymous binds. It's recommended that a proxy user is used that has sufficient rights to search the desired tree and attributes.
