[Samba] AD integration not working after move/version




Hi!

I am in a bit of trouble, I have moved a samba installation from one virtual host to another keeping the configuration files and filesystems. But during the transition something broke, now windows users are no longer able to access their shares. I think it has to do with the AD integration. I do not know it it because some state is missing on this host related to the AD integration or if something has changed since the version of samba is higher on the new host. We have the same set of private files also (passed.tbd and secrets.tbd).

Old version was 3.5.8 and the new version on the virtual host that does not work is 3.6.25.

Any ides on how to debug this is helpful, I know very little about AD integration, perhaps the virtual host needs to join the domain again and authenticate, can I check the status of the integration in any way?

Some error messages I was able to find:

Configuration, with user names and real paths removed, only change otherwise is that we had to change to ISO8859-1 for locale, not the argument “LOCALE” that was not longer supported.
