If you use version 3.0.12 or later, for most migrations the multi-group info 
should transfer OK. I am now aware that if the NT4 domain is post SP5 on some 
migrations multi-group info is not transferred and some account (both user 
and machine) password entries are not transferred either.

Maybe Andrew Bartlett will chime in on this?

Oops. That one needs updating. Thanks for pointing it out.
