[pmwiki-users] authuser.php crash (ref PITS 00737)

I just posted dbauth-0.2.php. This _should_ work better. Dbauth has no
knowledge of groups--it leaves Site.AuthUser to store those. It simply
expects username and password, and when it finds a match it returns
true.
I need to fix this script so the administrator does not have to edit
the recipe to set values. I'll try to get a newer version out _soon_.
The only problem is today is one of my long days in class (5 hours
straight). Being the first week, I have to actually pay attention. So,
expect the next release to include the site-specific flexibility.
After that, I should try to leave some integration hooks with
htpassword.php and membership.php. I would also like to add group
support and include the SQL to build an appropriate table.
As a word of background. I wrote dbauth to access the user table of a
PunBB forum--and had users register there to access a restricted site.
This was written well over a year ago and I have not tried to spruce
up the code. This past fortnight was my own private Summer of Code,
and I left that recipe out. Perhaps I can squeeze out one-more-week.

Ben Wilson
