c3pro-auth - a Spring Boot auth server for the C3-PRO platform.

This authentication server is a Spring Boot / DynamoDB port of the OAuth2 server portion of C3-PRO/c3-pro-server. The implementation was adapted from OAuth2Server, OAuthServerFilter, and RegisterServer.

Differences from C3-PRO

This implements the client-credentials OAuth2 flow as described with the exception of the use of "Authorization: Basic" rather than "Authentication: Basic" header while retrieving the authentication token.

The authentication database which stores the client credentials and manages access tokens for the resource server is configured to use DynamoDB rather than Oracle.
