I upgraded one of our servers from SLES SP2 to SP3 last night. Since then, people using Windows XP computers (we still have a few) and a Windows 2003 Server can’t login to the Linux box.
It gives a System error 1326: unknown user or bad password.
Windows 7 and Windows 10 have no such problem.
Can anyone give me a steer as to where to look / what to do?
Many thanks
Tim

Hi and welcome to the Forum 🙂
I would imagine security upgrades on the SLE system and out of date/insecure software on the hosts trying to connect…
How do you mean logging in, shares, ssh, vnc?
If it’s net shares then I imagine the hardening of samba/cifs on SP3.

Yes it is trying to connect to a Samba share.

Hi
You will need to make changes to the /etc/samba/smb.conf file and restart the smb and nmb seervices.
Try adding the following to the [global] section;
```auto
ntlm auth = yes
```
or
```auto
client use spnego = no
client ntlmv2 auth = no
max protocol = NT1
```

Your first option worked.
Thank you so much!
