In addition (and maybe even more important) I expect that "id -u <user>" prints the same result the same result as "id" prints out after <user> as logged in:

root@martnix4:~# su - user1
user1@martnix4:~$ id
uid=1002(user1) gid=1002(user1) groups=1002(user1)
user1@martnix4:~$ exit
logout
root@martnix4:~# su - user2
user1@martnix4:~$ id
uid=1002(user1) gid=1002(user1) groups=1002(user1),1003(somegroup)
user1@martnix4:~$ exit
logout
root@martnix4:~#

So, it really looks like a bug for me...

Best regards,
