[security-dev] Supporting different credential types from a single authentication endpoint

Hi, I would like to create a generic authentication endpoint using JAX-RS (with a single @Path for authentication) to support multiple credentials. Each credential type may have its own payload format, so I need to convert the payload to the correct implementation before authenticating. Do I have to use @Provider for this "dynamic" behavior ? Or there is a more easy way to achieve that ? What about using custom mime types for each credential type ? Thanks. Pedro Igor
