It's a very complicated and technical discovery process that I have
dubbed "guessing". :) (Actually, the best way is to use exim -bh to
test. That'll give you about as useful a bit of info as you're likely to
get. :)

Ok, so you've got libpam-pwdfile installed. Everything you've posted
from within your exim.conf appears to be in order. Make sure you've put
the plain: stuff inside the authentication section. That was one of the
first mistakes I made actually. :)
Next, check your /etc/pam.d/exim and make sure it looks a little
something like this:
account required pam_permit.so
auth required pam_pwdfile.so pwdfile /etc/exim/passwd
of course, you'll need to replace /etc/exim/passwd with the path to your
actual password file. Also double check to make sure you made the passwd
file and make sure you've got the same username/password combo in there
that you're trying to log in with. I used the script that Derrick posted
and it worked great for me. (not counting the fact that it's in python
and not perl, but I guess I can't win 'em all... :)
Then just do an "exim -bh 127.0.0.1" and then:
EHLO hereiam
AUTH BASIC <output of the base64 script using both \0's>
And it SHOULD work. (Should being the key term. If it doesn't, just post
the error message and we'll go from there.) Good luck. :)

p.s. And once you're done with that you can start messing around with
TLS support. That was my 2nd project and today I was able to, for the
first time ever, send mail from my home mail server while away from home
using username/password authentication over a secure connection. I was
so proud. :)
