Hi there, it's me again Well as many of you knows, I have a squid+ldap+digest_auth implementation. However I've realize that there are an excess of this logs: digest_pw_auth(LDAP_backend) WARNING, LDAP error 'No such object' digest_pw_auth(LDAP_backend) WARNING, LDAP error 'No such object' digest_pw_auth(LDAP_backend) WARNING, LDAP error 'No such object' digest_pw_auth(LDAP_backend) WARNING, LDAP error 'No such object' digest_pw_auth(LDAP_backend) WARNING, LDAP error 'No such object' digest_pw_auth(LDAP_backend) WARNING, LDAP error 'No such object' I know that this means that someone is trying to authenticate with an user that it does not exists in ldap. However they are so many and I afraid that this could be a cause that slows internet surfering because squid wates its time looking for something it does not exists. I dont know usernames users try. I just wonder if there is a way to tell squid to ignore usernames that they doesnt exists. Maybe an external ACL with 2 days cache? LD
