Don't really understand that, it sounds like it does and it doesn't work 
for you.

Yes, Ubuntu 22.04 using MATE, I do not use GDM, my opinion of that could 
not be published.

I have found out how to get winbind to log debug messages, I cannot find 
out how to obtain the lightdm message, but it appears to start 'Domain 
Controllers....'. If I log in with the network connected I get a number 
of lines in auth.log. If I disconnect the network and attempt to login, 
I get the same lines with one extra in the middle:

May 28 08:20:59 member1 lightdm: pam_winbind(lightdm:auth): User rowland 
logged on using cached credentials

So, if you follow the wiki (when it comes back) and it doesn't work, 
then it may not be a Samba problem, it may be a GDM problem.
