Hai.,we are using squid 3 in our network.,we need to configure the user authentication to this.,we configured like this
acl pass proxy_auth REQUIRED
acl mynetwork src 192.168.1.0/24
http_access allow pass
http_access allow mynetwork
But the authentication is not working.,whai i need to do? any more configuration needed..we are using rhel 4 OS...help me..

what kind of squid auth are you using? unix? ldap? ntlm? what error are you getting? are you getting an auth prompt? have you tried removeing the 'acl mynetwork src 192.168.1.0/24 & 'http_access allow mynetwork' lines? restarting squid /etc/init.d/squid restart? more information is needed.

We didn't get an authentication prompt..And also i tried without this two lines "acl mynetwork src 192.168.1.0/24 & http_access allow mynetwork" but access dined prompt occured.,we are using NIS for user sharing to our network.,

okay, show the the parts of your squid.conf file that you've setup authenitication in. Have you setup PAM authenitication in squid using NIS or how have youset it up, because i wasn;t aware that squid had NIS authenitication.

check out this how-to

Just setup PAM using NIS

for user based Authentication you need to use ncsa_auth just follow the step
which i am writing below ir will work.
#touch /etc/squid/squid_passwd
#chmod o+r /etc/squid/squid_passwd
#htpasswd /etc/squid/squid_passwd vishal
New password:
Re-type new password:
Adding password for user vishal

#
# Add this to the auth_param section of squid.conf
#
auth_param basic program /usr/lib/squid/ncsa_auth /etc/squid/squid_passwd

#
# Add this to the bottom of the ACL section of squid.conf
#
acl ncsa_users proxy_auth REQUIRED

#
# Add this at the top of the http_access section of squid.conf
#
http_access allow ncsa_users
