Hi There, I have recently installed Squid 2.6.STABLE21 for i686-PC-winnt. The proxy server is currently acting as a chained Proxy and will send all client HTTP request to an online web filtering site. I have managed to configure this correctly but I am having problems with LDAP. I have put the following code into the suid.conf file: auth_param basic program /squid/libexec/squid_ldap_auth -v 3 -b "dc=mydomain,dc=net" -D uid=ldap user,ou=IT Department,dc=mydomain,dc=net -w ******** -f uid=%s myserver.mydomain.net auth_param basic children 5 auth_param basic realm mydomain Server auth_param basic credentialsttl 5 hours But I get the following error from the squid.exe txt file: FATAL: auth_param basic program /squid/libexec/squid_ldap_auth: (2) No such file or directory Any idea what could be wrong? Thanks Duncan Peacock
