[Samba] Bad lockout attempt recorded 2x

[Jeremy Bender]

All,
I built and installed 3.0.7.  I am trying to finalize my setup by 
limiting the user to 3 failed logon attempts.
I used:
./pdbedit -P "bad lockout attempt" -C 3
This works fine for all users EXCEPT for the user with a matching 
Windows user name. In other words,
if my windows user name is 'bender' and my samba user name is 'bender' 
the number of Bad logon attempts
will continue to increment as other accounts logon's fail.

Example:
I logon to my Windows box as 'bender'
I also have the samba users 'bob', 'chuck' and 'bender'.  If I Map a 
Share as bob and mess up twice (or once) and then
successfully logon, the 'Bad password count' for 'bob' will correctly be 
0, but for bender it will be 2.  If I logon
as 'chuck' and mess up once - 'bender' is now locked out!!  Not only 
that, all the shares on my samba server are
locked out to EVERYONE until I either remove user 'bender' or
./pdbedit -z -c='[]' bender

I included smb.conf below although I doubt this matters much.

Thanks for any help!
Bender
