samba - Feb 2003 - RE: pam_unix.so likeauth? (Was: Help with Winbind)

It makes it work!  I was reading through the other messages on the list with
similar subjects, and found this one:

It was a long message, so I won't quote it again, but if you read back,
you'll find this message.  I just decided I'd try his pam setup and it
worked after I added the likeauth option.  I tend to just do whatever it
takes to make it work first and then go back and figure out what
consequences I'll run into afterwards...

Could you help my ignorance?  What does likeauth do
for you?  I'm only using use_first_pass, and I don't
want nullok.

In /usr/share/doc/pam-0.75/txts/pam.txt:
"The likeauth argument makes the module return the
same value when called as a credential setting module
and an authentication module.  This will help libpam
take a sane path through the auth component of your
configuration file."

That wasn't very helpful.

I Googled this option but didn't find anything useful.
 I didn't see an explanation of why you're using it in
this thread, either, unless I just missed it.

So could you explain, in human terms, how this helps
your setup?  (:

Thanks for the education,
