Hi all, I'm authentication with the ldap-helper "squid_ldap_auth" against an active directory. I can specify two credentials-ttls: One is possible in the "auth_param"-directive: auth_param basic credentialsttl 2 hour The other one looks like this: authenticate_ttl 1 hour What is the difference between this two options? Which option will be used, when I use the squid_ldap_auth-helper? Is the "authenticate_cache_garbage_interval" also possible, when I authenticate aginst an active-directory? Or is this directive in this case useless? Thanks a lot for your help. Tom
