Need to support logout

[jpotts]

Is there a way we can easily add support for logout? In the current code, if you logout, you'll get logged back in immediately because the logout action redirects to the Share page and Google retains your credentials, so you'll just be logged right back in again.

Hi @jpotts the share-oauth-sso depends on the scribe java library. I've checked if logout is supported by the API but that does not sound like it is.
In any case, logout would mean that we need to logout the user from the external Google session with the side effect of closing the session of all other related app session (GMail for example).Is this what you are looking for ?

On the other side, if the logout should be restricted to the Share session, it would be possible to add a "logout" cookie, or something similar, to the user and check the presence of this cookie in the filter process method (https://github.com/gdepourtales/share-oauth-sso/blob/master/src/main/java/ch/gadp/alfresco/OAuthSSOAuthenticationFilter.java#L393)
Setting thiscookie should be done while intercepting the Share logout request
