Samba 4 will happily use an existing smb.conf file but will complain if some of the settings in the current smb.conf file do not match the provision parameters. What's the exact error message you're getting?
I wonder if this is a dupe of bug 832465. ** Changed in: samba4 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/958957 Title: samba4 - smb.conf (already exist) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba4/+bug/958957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
