Java – the best way to authenticate users in Web Applications

I'm looking for ways to authenticate users in web applications, but the main web applications don't need to handle passwords Things like openid, but the authentication server must be hosted on the intranet, and the application server cannot access Internet services

My environment is almost Java Web applications, but connecting the system to other types of applications is also interesting

Solution

You can run your own openid server

You did not mention your environment, but if you are running in a Windows domain, another option is to use windows authentication for active directory
