Hello,
I currently try to mount a samba share with plaintext auth.
This works perfectly on linux box with smbfs, but I can't mount it
CIFS box (like kubuntu 8.04).
Under windows, with the good registry modification, I doesn't have problems.
samba version installed on the client: 3.0.28a-1ubuntu4.9
Here an output of 'modinfo cifs':
filename: /lib/modules/2.6.24-24-generic/kernel/fs/cifs/cifs.ko
version: 1.52

srcversion: 2CAF307257F44341D360511
depends:
vermagic: 2.6.24-24-generic SMP mod_unload 586
parm: CIFSMaxBufSize:Network buffer size (not including
header). Default: 16384 Range: 8192 to 130048 (int)
parm: cifs_min_rcv:Network buffers in pool. Default: 4
Range: 1 to 64 (int)
parm: cifs_min_small:Small network buffers in pool. Default:

parm: cifs_max_pending:Simultaneous requests to server.
Default: 50 Range: 2 to 256 (int)
CIFS module compiled with CONFIG_CIFS_WEAK_PW_HASH enabled
/proc/fs/cifs/SecurityFlags setup with "39" (0x27 in Hex)
added theses lines into /etc/samba/smb.conf:
client plaintext auth=yes
client lanman auth=yes
client ntlmv2 auth=no
and rebooted the box (and re-setup 39 in /proc/fs/cifs/SecurityFlags).
Now, try to mount:
root at P126:~# mount.cifs //10.66.232.12/dev_users share/ -o
username=G132248 --verbose
Password:
mount.cifs kernel mount options:
unc=//10.66.232.12\dev_users,ip=10.66.232.12,ver=1,username=G132248,pass=********
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
