Hello Guys,
The modifications below to winbindd_pam.c solved the issue of non
joined computers expect for clients using Internet Explorer (tested
with IE7) only on Vista HOME edition!
It worked fine on all other versions of widows win2k, Window$ XP,
Vista premium, etc.
Did you guys face this?
Thanks,
Samer
