make_filter: cope with filters that are already parenthesized Treat filter elements correctly that may be more complex filters themselves; e.g. '(&(sn=Doe)(givenname=John))'

run_list: new argument syntax: [<options>] [<filter>] [<attributes>] From 232fbd24ff43c9c0d0691cf0e1b51a82ef099489 Mon Sep 17 00:00:00 2001 Make run_list work with a properly defined argument syntax: - start with (optional) options: -R -l - continue with filter ['(objectclass=*)' as fallback if none given] - end with attributes (also optional) Add method is_valid_filter() to check whether a strig is a legal LDAP filter.

fix attribute lists for LDAP queries LDAP does not know of an attribute named 'dn'. To get only the DN in a search, the attriibute list to use is '1.1'. On all other cases, the DN of the entries found is automaticlly part of the result set too.
