[Samba] Samba 3.0.28a integration with 2003 AD and password lockout policy?

[Braebaum, Neil]

I'm encountering some oddness using Samba 3.0.28a, MIT kerberos (1.6.3)
for user authentication on Linux, to 2003 Active Directory.

The password policy dictated by AD should lock accounts after 6
incorrect login attempts within a 30 minute period. However, it seems to
halve that when logging in to these Linux boxes via ssh - so after 3
incorrect login attempts, the AD account gets locked.

Looking in log.wb-<Domain Name> seems to show double attempts /
authentication failures when submitting the login with an incorrect
password (to test this).

I have noted password level in smb.conf (it's not set in my smb.conf),
but as I'm using encrypt passwords = yes, I thought it was irrelevant.

It would appear that two submissions are being made, though, is that a
Samba version thing, something I may have not got spot on with my pam
configuration, or an issue with the Samba version?

testparm output follows:-

Load smb config files from /usr/lib/smb.conf
Loaded services file OK.
'winbind separator = +' might cause problems with group membership.
Server role: ROLE_DOMAIN_MEMBER
