recently we've upgraded our server distro (Ubuntu gutsy to hardy), and as a side effect, older Samba clients (Win95, mostly) are now unable to connect (it keeps asking their password). I have been unable to retrieve meaningful information from samba logs, currently.
1) Has anyone encountered such a problem, and if yes, what is the cause of it/how it can be fixed? I don't know if moving to e.g. user-level security is an acceptable solution.
2) If not, where and how should I dig?
