samba - Nov 2000 - Mysterious user authentication failure on basic network

Problem: Win PC users can't authenticate on simple network.

Situation: Linux RH7.0 samba server on 192.168.0.0 network is sharing data
to one or more Win95/98 PCs running static IPs. No NT, nothing complex.

Server APPEARS in PC browse lists but won't display shares and generates the
$IPC password requuired when the windows PC tries to access the share.

I have gone right throught the diagnosis tips (twice) and can confirm that
the Linux is master browser on the one correct subnet, network/workgroup
names are same on server/PC, linux user names and password match windows
usernames and password but no mapping.

The only problem I can find from the diagnosis tips is that from linux if I
type "smbclient -L MYSERVER" it says:

"SSL: Error error setting CA cert locations: error 00000000:: lib(0):
func(0): reason (0)" and then asks for password. If I enter over pasword
the
anonymous user will be able to display the linux shares. This is only from
linux, if I do it from windows (ie net view \\server or net use x:
\\server\tmp) I get password prompts and then authentication failures for
any likely password or blank password which appear in
/var/log/win9cname.log. These logs show simply "username
""authentication
failure".

I have tried differnet PCs. Win95/98 and changed the netowrk name etc all to
no avail.

HELP..! What should I try next. Is the CA cert significant ie needed for
authentication?

Thanks in advance.

Hi Bill,

Good on you mate! Thanks for your reply. Whilst trying encrypted passwords
in smb.conf was something I had tried already without success, your pointer
to encryption as the cause was of course spot on. I made the clear text
registry entry changes to both Win95B and Win98SE PCs and all worked
perfectly. In short, I agree with you and I think that SAMBA and Windows
don't always get their encryption alligned (no really rigorous hard
research, just a hunch of mine at this stage but I found that my SAMBA
server talked on a 2m piece of coax to a Win95B machine and simply worked
first time but when I moved the SAMBA server to a larger live network that
was when the encryption problem got me.)

 *** Clear text solved the problem ***

The only unresolved issue that is playing on my mind is why one Win95B PC
worked first time whereas another Win95B PC needed the registry changed to
clear text before it would work..... anyway, since it works I am happy for
now and can overlook this apparent mystery.

I hope this info helps someone else too and saves them the 2 late nights I
have had on this one ...

Many thanks again for your help Bill.
