Hi, long time, no see...

I can do this manually simply enough with a quick split and a map, but I suspect that the problem is common enough and possibly more complicated than I first thought to have been solved by a module. I cannot find such a module; I've looked at LDAP::uri and Net::LDAP, but I can't find anything that does what I think I want

I have a plain text string, containing an LDAP dn. It looks similar to this

cn=John Bull,ou=admins,ou=technical,ou=Staff,dc=example,dc=com
[download]

and I want to parse that such that I can easily answer the questions "Is user $foo in group $bar?", "Show me all the members of group $baz". Is there a module which does it for me?
