samba - Jun 2017 - windows 2003 can not login with samba 4.6.4

Hi,


We have upgrade samba from 3.6.23-36 to 4.6.4, but we got "*Logon Failure
Unknown user name or bad password*" error while trying to access samba form
window 2003. And we use usename and password to login, not by the AD.
We also test on windows2008 windows2008-R2 window7 windows10, it works.


Thanks.

You should enable the group policies to have Windows 2003 use NTLMv2.

Otherwise, if you can't do that, set 'ntlm auth = yes' (NTLMv1 is
not
considered secure these days, so was disabled in Samba 4.5 by default).

I hope this helps,
