This is not installed correctly. See my previous reply:

This is not the tests I asked you to run. See my previous reply:

To clarify

Run /usr/lib/squid/pam_auth from the command line. Then give lines
consisting of username <space> password <enter> as input to the
program while it is running. If it works the program will respond
with OK/ERR, once per line of input.
