[Samba] "Bad lockout attempt" recorded twice

[bender at twcny.rr.com]

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
