thanks but...
thanks a lot for unclepips's guide.
i have joined domain now, but i get new problem.
i can't get next step when that has ran 「waiting for http...Done」.
just like freeze ,but web gui was normal for a short time, then all system freeze....
after long test, i get some information as below.
at shell, i type 「wbinfo -u」 and 「wbinfo -g」 just show one message as error balabala(sorry, i forget it)
but type 「net ads info」 that show i connect LDAP server
i setting use AD but it's connect LDAP server, so is it right?
