[Samba] Security share and problem with unix groups login.

[nietykalny at orange.pl]

I've expirienced strange problem with unix group login in samba recently. This is 
unusuall because users given in "username" pramater in share can log into it, but if I 
add group of users that group cant log in to share. I'm using FreeBSD 6.2 Stable, 
samba version is 3.0.25.a. Sample smbd logs:
 
[2007/08/21 16:49:39, 3, effective(0, 0), real(0, 0)] libsmb/
ntlm_check.c:ntlm_password_check(455)
  ntlm_password_check: LM password, NT MD4 password in LM field and LMv2 
failed for user xxx
[2007/08/21 16:49:39, 3, effective(0, 0), real(0, 0)] smbd/
sec_ctx.c:push_sec_ctx(208)

Cheers.
