[teiid-issues] [JBoss JIRA] (TEIID-5780) Support certificate based authentication into Teiid pg

[Steven Hawkins (Jira)]

    [ https://issues.jboss.org/browse/TEIID-5780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13750254#comment-13750254 ] 

Steven Hawkins commented on TEIID-5780:
---------------------------------------

To allow the ssl transport to be reused, we'll need to add another authentication mode where where want, but don't require client auth (in the first commit).  This would not yet be the pg certificate authentication type.

However I'm uneasy about creating a subject that may or may not exist in the realm.  If we instead require an admin user to be created in the realm that could simplify things, but may introduce issues around password expiration.

> To support the pg connection into Teiid we will do something like:
> - require a pg secure port using the service signing certificate: TEIIDSB-90 TEIIDSB-92
> -- one clarification is that we must document how to make the pg cert dominant if both pg and jdbc secure are used
> TODO:
> - configure the pg instance to have a service signing certificate and trust the Teiid service signing certificate.  If that trust seems too difficult we can just configure the connection to trust all.
> - configure the pg connection to Teiid to use the pg service signing certificate as the client certificate
> - trust the pg service signing certificate at the teiid service - we need hostname validation to be enabled and the Teiid server to map the service host name to an authenticated user (this could possibly be generalized via keycloak support to more users).
