This module uses basic authentication, which is the HTTP protocol’s built-in authentication support. The web server issues a client request for username and password, and sends that information back to the server as part of the authorized request. Access Manager retrieves the username and password and then internally authenticates the user to the LDAP authentication module. In order for HTTP Basic to function correctly, the LDAP authentication module must be added (adding the HTTP Basic module alone will not work). Once the user successfully authenticates, the user will be able to re-authenticate without being prompted for username and password.
