Samba4 New Issue after upgrade to 4.1.x
 

I have updated samba 4 from version 4.06 to 4.1.0 rc3 but I am having problems:

When trying to connect a win7 box to the domain I get password expired for the domain admin.

I have tried to reset the password to no avail:

It seems there are some issues here with Kerberos; anyone have any ideas?

I get almost the same errors with version 4.0.8.

Did you get your 4.0.6 running?

Hi Warnerk,

No; though there is a much more up to date version at Samba 4.1.0 RC4 so over the next few nights when I get an opportunity I am going to wipe the server and start again on Debian Wheezy 7.1 using this newer version of Samba and will then see what the outcome is again.

It's quite an interesting piece of software and I'm keen to get it working properly in a stable and predictable manner as then I don't have to bother with Windows servers at home at all.

Though we will always be using Windows Desktop clients hence the need for Samba4 (as I need active directory and group policies).


I'll report back my findings.
