Subject RE: OpenCMIS SSO authentication provider
Date Mon, 29 Oct 2018 21:19:15 GMT
Hi Florian,

Thanks for the detail.   I think there is no problem for extract the data in the CallContextHandler.
 The question is where we do the authentication in OpenCMIS Server Framework, is the getService()
in service factory a good place to do the customized authentication?

Hi Wentao,

build a servlet filter in front of the OpenCMIS bridge that handles the 
authentication. You should be able to trigger the authentication 
mechanisms of the application server there, if you need that.
In that filter, stick all data about the user you need in the bridge 
into request attributes. Now you are free to use that data in the 
CallContextHandler, the service factory, or in each call.

The OpenCMIS server framework only supports basic auth and there is 
nothing else planned.
