Hi, I'm trying to get LDAP authentication working on my squid proxy. Now ideally I would like to only allow users in a certain group (namely, cn=squid,ou=Group,dc=ph,dc=sun,dc=ac,dc=za which is a groupOfUniqueNames (does this work or must I use an objectClass=posixGroup?) to authenticate and use the proxy. How would I go about doing this? I've added the following lines to my squid.conf file: auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hour auth_param basic casesensitive off auth_param basic program /usr/lib/squid/squid_ldap_auth -b "ou=People,dc=ph,dc=sun,dc=ac,dc=za" -f "cn=squid" -s sub fsk.ph.sun.ac.za external_acl_type ldap_group %LOGIN /usr/lib/squid/squid_ldap_group -ZZ -b "ou=Group,dc=ph,dc=sun,dc=ac,dc=za" -f "(&(objectclass=groupOfUniqueNames)(cn=%a)(uniqueMember=%v))" -B "ou=People,dc=ph,dc=sun,dc=ac,dc=za" -F uid="%s" fsk.ph.sun.ac.za acl password proxy_auth REQUIRED acl password_group external ldap_group squid http_access allow password_group Any help would be appreciated!
