[squid-users] Help! setting up squid to authenticate through accounts passwords

I need help how to setup squid to authenticate using ncsa or pam.

I am new to squid. I am using Redhat 6.2 and squid 2.3. I would like to
limit access through squid-cache by authenticating the users through
there account password already on the local server (on the same machine).

I tried the instructions for ncsa_auth, that is, to 'make' in
auth_modules/NCSA but I am having the following error

> gcc -g ncsa_auth.o -o ncsa_auth -L../../lib -lmiscutil -lcrypt -lm
> -lresolv -lbsd -lnsl
> /usr/bin/ld: Cannot find -lmiscutil
> Collect2: ld returned 1 Exit Status
> Make: *** [ncsa_auth] Error 1

I have also tried to add the following lines to my squid.conf:
-------------------------------------
authenticate_program pam_auth shadow
authenticate_children 10
authenticate_ttl 3600
authenticate_ip_ttl 0
acl password proxy_auth REQUIRED
acl user1 src 10.30.0.5/255.255.255.255
http:_access allow user1 password
--------------------------------------
This doesn't work. Where am I going wrong??
