Sure you can use the same group names - provided that they don't contain any characters that AD does not except.
Not sure I understand the question about the launcher? The "open remote" dialog shows all the databases already.
If you have an existing launcher, it should still work.
Thanks for the response!
I'll try the AD groups and see how it goes. Nevermind about the launcher. I just had to convert my old one to fmp12 format.
