Re: [squid-users] getpwnam syntax

Hi Henrik, thanks for the quick response! Funny you should suggest
PAM. The trouble is that I thought this was the way to go as well in
the beginning, but I ended up with a bunch of warnings and errors in
the make. I did this for the config script:

./configure --enable-basic-auth-helpers=PAM

And that seemed to do okay. But when I issued the 'make' I got a lot
of stuff like this:

I spent half a day googling around for solutions to this before I
moved on to the idea of using getpwnam. However, I would much rather
use PAM if I can get it working. Any suggestions on the above? Thanks!
