[teiid-issues] [JBoss JIRA] (TEIID-4552) Missing support for connection to Facebook via OAuth 2

[Jan Stastny (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13376230#comment-13376230 ] 

Jan Stastny commented on TEIID-4552:
------------------------------------

I believe that has to be a change in the login module too, to support refresh_token-less use cases.

I remember that at least LinkedIn and Strava social sites, don't use refresh_token at all. I think they use long-lasting access_token instead.

Sort of a workaround would be to allow configuring access_token directly in the resource-adapter's security domain. Is this something we want, or are there some concerns?
To illustrate what I am talking about look at this diff: https://github.com/teiid/teiid/compare/master...jstastny-cz:oauth2-accesstoken 
The idea was to bypass refreshing the token, if access_token is provided from the configuration of security-domain.

> I would like to connect to facebook resource adapter and configure OAuth 2 security domain for it; I used teiid-oauth-util.sh to generate the security domain (see attachment). Facebook doesn't support refresh tokens and in the generated code is refresh token's value "null".
> If I try to execute VDB with source pointing to such resource adapter I get error:
>  ERROR [org.teiid.CONNECTOR] (Worker0_QueryProcessorQueue13) Connector worker process failed for atomic-request=Gapuea1/NRcn.6.3.0: org.apache.cxf.rs.security.oauth2.provider.OAuthServiceException
>  
> (see server.log, facebook-vdb.xml, standalone.xml)
