Cacti is a great tool and it permits you to set up for HTTP authentication (Web Basic Authentication). However, I have had a couple of configuration issues when setting up HTTP authentication and have needed to put Cacti back to “Builtin Authentication” – but you cant do that if you cant log in!

To set Cacti back to “Builtin Authentication”, or “None” use mysql to connect to the cacti database, then issue one of the following mysql commands

update settings set value=0 where name="auth_method";

The above will set it to no authentication

update settings set value=1 where name="auth_method";

The above will set Cacti to “Builtin Authentication
