This proposal introduces the AuthenticationManagerResolver<GrpcServerRequest> to Spring's gRPC authentication framework. This provides a flexible mechanism for implementing dynamic authentication based on your specific needs.

The Problem:

  • Traditional Spring gRPC authentication relies on fixed configuration of authentication providers, limiting flexibility.
  • Changing authentication mechanisms requires code modifications and redeployments.

The Solution:

  • Introduce AuthenticationManagerResolver:
    • Allows dynamic selection of the AuthenticationManager based on the gRPC request.
    • Enables fine-grained control over authentication based on request headers, payload, or other criteria.

Nice suggestion, I'm currently quite busy so I might be slow to respond.

Great, I've fixed the merge conflicts that arose due to the file movements. I've carefully reviewed the changes and believe everything is now in sync.

I've pushed the changes to the branch. Could you please take a look at the latest version and let me know if you have any further questions or require additional modifications?

Implementation wise looks good to me, but I have no time to check the security/config side effects.

I haven't tested this myself and I'm unsure about the change in condition regarding when the security config is enabled.

Other than that, it looks good to me.

I haven't tested this myself and I'm unsure about the change in condition regarding when the security config is enabled.

Other than that, it looks good to me.

If on of the interceptors condition met, then it will be registered. On the other hand if both conditions met then the first one will be registered according to the priority.

According to existing GrpcServerSecurityAutoConfiguration Conditions, if GrpcAuthenticationReader is not registered, I think it will probably encounter error. So all the configuration depends on GrpcAuthenticationReader.

If you have any other situation to consider, please let me know.
