Thanks for that, I have installed the helper but am getting stuck on the configuration side. Could you point me to some documentation which explains how to configure squid.conf. I have tried auth_param digest program /usr/local/squid/libexec/digest_ldap_auth -e -b "OU=UserAccounts,OU=Users,DC=MY,DC=DOMAIN,DC=AC,DC=ZA" -F "uid=%s" -D "Cn=User_Name,OU=ServiceAccount,DC=MY,DC=DOMAIN,DC=AC,DC=ZA" -w "Pass_Word" -h 146.141.x.x -p 636 -v 3 -Z With the above conf, cache.log give me the following: helperOpenServers: Starting 5 'digest_ldap_auth' processes Usage: digest_pw_auth(LDAP_backend) -b basedn -f filter [options] ldap_server_name (with and explanation of all the switches that can be used e.g. -A password attribute(REQUIRED) etc...) The messages log shows: Apr 10 09:22:06 chuck squid[31319]: Squid Parent: child process 31340 started Apr 10 09:22:06 chuck (squid): The digestauthenticator helpers are crashing too rapidly, need help!

It works fine for plain text files but not for LDAP. In Squid-3 there is a digest_ldap_auth helper in helpers/digest/ldap/. This helper works fine with Squid 2.5 as well even if it is only found in the Squid-3 tree. Squid-3 is found either from the CVS or as nightly snapshots from the home page.. The LDAP digest helper can access either plain-text or Digest hashed passwords from LDAP. Regards Henrik
