User authentication for Explicit Proxy

We support firewall LDAP-based user authentication to control user access to the network for explicit web-proxy deployments. We support web authentication with web redirection and usage of captive portals. With explicit web proxy authentication in place, when a user first connects to the proxy server, the browser is prompted to provide their credentials. The explicit proxy then verifies the username and password with the LDAP server. If the credentials are valid, the proxy grants access to the client and stores their information in the database.
