This module, primarilly the work of "Stefan (metze) Metzmacher"
<metze@metzemix.de>, uses the Active Directory schema to store the
user/group/other information. I've been testing it against a real AD server,
and it is intended to work with OpenLDAP as well.
I've moved a few functions around in our other libads code, which has made it
easier to tap into that existing code.
Also, I've made some changes to the SAM interface, I hope there are not too
many objections... To ensure we don't get silly bugs in the skel module, it
is now in the default compile. This way you should not forget to update it :-)
