Connecting NT 4.0 clients to a SAMBA 4.17.9-Debian server

This is a brief but annoying thing.

I want to have an internet server that people can map drives to, for copying data in/out for the upcoming Dec Alpha AXP64 building extravaganza! I wan tot use my Dec Alpha for building since it’s got a gigabyte of RAM. One of the hard parts is that NT 4 is beyond obsolete, and twice as much on the DEC Alpha. I was figuring renting a VPS, and using it as a SAMBA server so people can simply map a drive from home, copy files to the VPS, terminal server to the Alpha, and copy files to & from the internet. Easy right?!

I was non stop getting this error:

System error 1326 has occurred.

Login failure: unknown user name or bad password.

Except I knew the username & password was correct.

The key part involved a few parameters to get it working. Although many people reported success by simply setting the protocol level, for me I had to set that and the lanman/ntlm auth to yes. Trying to enable NT4 compatible encryption didn’t work either.

   workgroup = WORKGROUP
   server min protocol = NT1
   client min protocol = NT1
   lanman auth=yes
   ntlm auth=yes

I’m not sure if it’s all that helpful to the world at large, or if it’s just super common knowledge, but I haven’t setup SAMBA in like forever. I guess I could go one further and join it to the domain but that doesn’t seem like it’s all that needed or all that smart.

  1. You shouldn’t need lanman as that’s for dos/win9x, NT4 should happily speak NTLMv1, or even NTLMv2 if you have NT4/sp4 or higher.
    What you do need however is SMBv1, as you won’t have support for SMBv2/SMBv3. Newer versions of win10+ will refuse to use SMBv1 by default so you’ll also need newer versions supported on the samba server if you want to share files between those hosts.

    • Thats a good idea, I should try some old lanman os/2 or dos client! I wasn’t even thinking of stuff that old!

      I just use a Windows NT 4.0 server with AppleTalk & NetWare services for old stuff, but for some reason I wasn’t thinking of LanMan. I do have NetBEUI enabled, but I don’t think SAMBA ever supported that.
