Here are my 2 cents. It's not a complete review, just a quick bugfix for the
"userInGroup" function, because I've reused it myself in a project.

https://codereview.appspot.com/101310044/diff/20001/src/pkg/os/user/lookup_un...
File src/pkg/os/user/lookup_unix.go (right):

https://codereview.appspot.com/101310044/diff/20001/src/pkg/os/user/lookup_un...
src/pkg/os/user/lookup_unix.go:199: gid, err := strconv.Atoi(g.Gid)
I think you rather want u.Gid here.  The getgrouplist(3) manpage says:

       If it was not among the groups defined for user in the group
       database, then group is included in the list of groups returned by
       getgrouplist(); typically this argument is specified as the group ID
       from the password record for user.

Currently, with g.Gid here, the group we want to check is always added to the
resulting list from mygetgrouplist, meaning userInGroup(u,g) always returns
true...
