[PATCH] 2.0.7-pre1, option to dissable sessio_users list.

[Mattias.Gronlund]

Hi,

In search for nameserver-load generated by SAMBA I found out
that most of the calls where made with getpwnam with usernames
that I do not think will succeed at that many sites at all.

This patch adds a new option to SAMBA "session users" that is
defaulted to True to behave as before. But if it is set to
False the session_users list will not be used. I

Any comments ?
