cyberjuls2 & all
Can someone confirm this?
I don't yet have Windows 8 so my comments are based on google search results.
There appears to be 2 issues, one is the ability to join the domain, the other is the ability to login as a user.
Some tweaks will allow the domain to be joined, but not allow a user to login, so that may be the source of these "rumours".
There is a further issue as to whether smb2 is being used or is disabled on the Windows 8 PC.
My earlier reading (googling) suggested samba4 or (maybe) minimally samba 3.7.x was needed to support both domain joining & user login by a Windows 8 workstation.
This post
http://www.mail-archive.com/samba@lists.samba.org/msg121155.htmlsuggests that with samba 3.6.6 on the Linux domain controller, a Windows 8 PC (with smb2 enabled & with the Windows 7 registry tweaks in place) can join the domain , but does not support user login.
If smb2 is disabled on Windows 8 then domain joining & user login is possible, but there are some issues with logging off.
Also disabling smb2 on the domain controller seemed to also allow Windows 8 domain joining & user login.
There was further talk in that thread about smb.conf entries & possible adjustments to ports that may help resolve issues, but I'm not sure of the significance or usefulness of that.
So regarding sme8.1 server, on a quick read it seems a more recent version of samba is required than what sme8.1 currently has ie it has samba3x-3.5.10-0.110.el5_8
Can Windows 8 login to a samba 3.5.x domain as well as support user logins. It appears to be no, not with the current sme8.1 packages.
If samba was upgraded, and the tweaks referred to above were made then it seems possible, currently with minor issues.
