--- Begin Message ---Package: samba Version: 3.0.28-1~lenny1 Severity: normal Since an upgrade (I can not tell you which one), my Windows 98 client is no longer able to access a shared home directory. I log on Windows using a valid user/pass added by "smbpasswd -a user". From a XP client, the access is OK. I didn't find out why this happens. On month ago, it works as usual. I edited nothing. So I think it's a bug... Or at least, debconf should notify a behaviour change and suggest a solution. Hope this help! ;) Here is my my smb.conf : # # Sample configuration file for the Samba suite for Debian GNU/Linux. # # # This is the main Samba configuration file.

This is documented in NEWS.Debian: samba (3.0.27a-2) unstable; urgency=low * Weak authentication methods are disabled by default Beginning with this version, plaintext authentication is disabled for clients and lanman authentication is disabled for both clients and servers. Lanman authentication is not needed for Windows NT/2000/XP/Vista, Mac OS X or Samba, but if you still have Windows 95/98/ME clients (or servers) you may need to set lanman auth (or client lanman auth) to yes in your smb.conf. The "lanman auth = no" setting will also cause lanman password hashes to be deleted from smbpasswd and prevent new ones from being written, so that these can't be subjected to brute-force password attacks. This means that re-enabling lanman auth after it has been disabled is more difficult; it is therefore advisable that you re-enable the option as soon as possible if you think you will need to support Win9x clients. Client support for plaintext passwords is not needed for recent Windows servers, and in fact this behavior change makes the Samba client behave in a manner consistent with all Windows clients later than Windows 98. However, if you need to connect to a Samba server that does not have encrypted password support enabled, or to another server that does not support NTLM authentication, you will need to set "client plaintext auth = yes" and "client lanman auth = yes" in smb.conf. So I'm afraid this is not a bug, but a deliberate behavior change. Debian has made this change slightly before upstream, but upstream is doing the same thing starting with 3.2.0 which is due to be released next month. To support Win98 again, you'll want to set "lanman auth = yes". It is recommended that you use apt-listchanges on your system, to be notified of package behavior changes such as this. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
