LDAP get the schema type (say rfc)

Hi All,

1. Is there is any method in Net::LDAP that can gives me an LDAP
Schema type say RFC33.. or Windows AD.
Since such a standard schema contains all static attribute properties,
so that can help me to add that schema into my tool.
2. Is there any way from which I can able to get the User/Group
attributes by giving OU Path.
Say : ou=a, dc=b, dc=c
Now Create some OU object and do OU->getattributes(); something like
this?

Thanks,
Omi
