Hi all,

I have been upgrading the samba package on a SLES10 (i686) machine with 
the new SerNet 3.5.3 package.
The server is using the ldap backend for users and passwords.
It has been working fine until I tried to use a DOS lan manager client.
A normal user was not able to "net use * \\server\share" and 
authenticate using the userid and password.
The error message in the smbd.log file was NT_WRONG_PASSWORD.
I have made no changes to the smb.conf file between the two binary versions.
If I switch back from 3.5.3 to 3.0.28, the user is able to log map the 

Is there something that has changed between the two that disables the 
possibility to use a DOS client with samba ?

The relevant pieces from smb.conf:

passdb backend = ldapsam:ldap://
security = user
encrypt passwords = Yes
domain logons = yes
os level = 35
acl compatibility = Auto
client lanman auth = no
null passwords = true

Thanks for any help!
