Patch originally from Kevin Ruddy, smiles@powerdog.com. Note that it
uses YP routines directly, rather than using getpwnam (which invokes
YP on machines that use it, and *works* on machines that don't).
Still, the idea may be worth considering...




OK, actually, this is specifically for 1.4 but I had originally put it into
1.3, so you can do that too if you want. It probably would fit fine into
Apache as well, but I haven't tried that yet.

What his patch does is permit people to say "AuthUserFile +" and then
it will allow the use of NIS to find username-password information
instead of special password files for httpd.

Regarding copyright: you can do anything you want with this patch. A
mention of my name would satisfy my ego but I won't require it. Guess
that makes it public domain.

Enjoy!!
