JHT came up with a nasty (broken) torture case in preparing examples for
his book. This prompted me to look at the code that reads the unix group list. This code did a lot of name -> uid -> name -> sid translations, which caused problems. Instead, we now do just name->sid I also cleaned up some interfaces, and client tools. Andrew Bartlett (This used to be commit f9e59f8bc06fae7e5c8cb0980947f78942dc25c0)
