Hello, Thank you always for your kind support. I would like to ask you about SEND_ERR reply of ext_ldap_group_acl. In our environment, squid fail ldap_bind to LDAP server sometimes. Then, ext_ldap_group_acl replies "ERR". So, username is registered in the negative_cache. I don't want to register in the negative_cache when external_acl failed ldap_bind. I guess that to solve if ext_ldap_group_acl reply SEND_BH instead of SEND_ERR. I would appreciate it if you could investigate this.
