[Samba] Assistance needed on using mount.smbfs (cifs) to authenticate to samba server with encrypt passwords = No.
Greetings, I am working on getting mount.cifs version: 1.11-3.2.4 on debian to mount a share on a samba server Version 3.0.13-1.1-SUSE on SuSe. This was working on older debian systems, but upon upgrading some of the systems to Lenny I am now having trouble mounting shares. Again, this was working and I have smbfs installed on the systems (which is what I used before). The samba server is set to have encrypt passwords = No and I am basically authenticating from /etc/passwd+shadow (no smbpasswd file). The setup is still working fine on non upgraded systems. Only on the newly upgraded systems is the mounting not working. The kernel on the clients do have CONFIG_CIFS_WEAK_PW_HASH=y Below is some dmesg info after running the mount.cifs with various / proc/fs/cifs/SecurityFlags: mount.smbfs //172.16.0.8/tech ./mymount

Many thanks.I'm not sure whether the following hints will also work with older cifs versions, it worked here with the recent git tree. 1.) use 'modprobe cifs' to load the kernel module 2.) use 'echo 0x20 > /proc/fs/cifs/SecurityFlags' (also try 0x27) 3.) mount by using the "sec=lanman" option, e.g. mount -t cifs //server/share /mount/point -o cred=/path/to/creds_file,sec=lanman I had a short look at the recent git cifs sources. The current plaintext auth codepaths seem to be a bit inconsistant and possibly not very well tested. (that auth type is a bit outdated these days ...) Cheers, G?nter
