Hi, I have a problem with samba-2.0.3. Currently, I am running samba 1.9.17p4 on our IBM RS/6000 (AIX 3.2.5) machines and some Linux machines. It is working well. I set up "EnablePlainTextPassword" on NT with SP3, and there is no problem. Now, I downloaded samba-2.0.3, compiled it on AIX 3.2.5, and installed it. When I run testparm, it does not show error message with the following smb.conf file: [global] workgroup = abcxyz browseable = yes load printers = yes printcap name = /etc/qconfig printing = bsd print command = /bin/lpr -h -P%p %s guest account = msnet status = yes log file = /usr/local/samba/var/log.%m log level = 1 max log size = 50 security = server password server = xyz dead time = 10 socket options = TCP_NODELAY [homes] comment = Home Directories browseable = yes read only = no ...... (some other shared directories) where xyz is my NT server (PDC). However, I can not mount any drive on AIX systems from any Windows NT or 95 systems -- always "password incorrect" as if I did not set "EnablePlainTextPassword". If I include domain controller = xyz in the [global] section, then I got an error message when I run testparm: Load smb config files from /usr/local/samba/lib/smb.conf Unknown parameter encountered: "domain controller" Ignoring unknown parameter "domain controller" Loaded services file OK. Press enter to see a dump of your service definitions ...... (it still lists all shared directories, but I still can not see any of them from NT or 95). Can somebody help me to figure out why? Again, I set up "EnablePlainTextPassword" on both NT and 95 machines, and it was working with samba-1.9.17p4. I tested: if I did not set up "EnablePlainTextPassword" on NT with SP3, then I can not see shared directories on samba-1.9.17p4 from NT with SP3 as expected. Thanks for any help! Hongwei Li
