I configured our squid to authenticate with squid_ldap_auth & squid_ldap_group against an active-directory. With the parameter "-h [ip-address of domain-controller], I'm able to define one ore more of our ldapservers (domain-controllers) for querying. But the setting with the specified failover-dc seems not really to work. How can I define a 2nd or a third domain-controller, if the request to the first domain-controller fails? How can I define a query-timeout? Thanks a lot. Tom
