Re: OpenLdap + Samba + Ubuntu Server 8.10
Some sanity-check questions.
Did you get all the way through all 3 pages of the tutorial? You didn't mention bind or your bind.conf.
Are you using XP Pro? Home will not work as they cannot join a Domain. Are the computers Domain members? Or is that where you are getting the denied error? Sometimes it is possible to enter credentials differently to authenticate. Instead of just user it could be DOMAIN\user or user@domain.
The how-to does not mention kerberos, but I know to connect the other way Ubuntu client to Windows domain you need kerberos to authenticate.
Have you looked up any other how-tos on this subject?
I see that most of the Google links simply point to copies of the how-to that you used.
