What is Knox SSO?

Apache Knox Single Sign-On (SSO) is a feature of the Apache Knox gateway that allows users to authenticate once and access multiple services without having to re-enter their credentials for each service. This feature provides a centralized authentication mechanism for multiple web applications and services that are protected by the Apache Knox gateway. When a user attempts to access a protected service, the Apache Knox SSO feature redirects the user to an authentication provider (such as Kerberos, LDAP or Active Directory) to authenticate their credentials. Once the user is authenticated, a token is generated and sent back to the user's browser. This token is then used to authenticate the user for all subsequent requests to protected services through the Apache Knox gateway. This feature greatly simplifies the process of accessing multiple web applications and services, as it eliminates the need for users to manually enter their credentials for each service. It also provides better security, as it eliminates the need to store multiple sets of user credentials for different services.
