Be able to intercept and process oauth principal into gatein user according to provider types --------------------------------------------------------------------------------------------- Key: GTNPORTAL-3414 URL: https://issues.jboss.org/browse/GTNPORTAL-3414 Project: GateIn Portal Issue Type: Enhancement Security Level: Public(Everyone can see) Reporter: Tuyen Nguyen The Assignee: Trong Tran Fix For: 3.7.0.Final, 3.8.0.Final Attachments: linkedin-registration.png Original Estimate: 4 hours Time Spent: 7 hours Remaining Estimate: 0 minutes When i register new account with LinkedIn, i see a registration form with random-string username prefilled (see attachment) It's because LinkedIn does not provide username as unique attribute for each user, so we have to get userid instead of username, and this is a random-string by LinkedIn Now, We can improvement method OAuthUtils#convertOAuthPrincipalToGateInUser() and customize the way to convert oauth-principal to gatein user for linkedIn. But when someone provide other oauth integration via extension, he can not customize OAuthUtils#convertOAuthPrincipalToGateInUser() method to generate gatein user by the way that oauth should do. So we should enable developer change the way to generate gatein user for each oauth provider via extension. To enable developer change the way to generate gatein user via extension, we will: - Introduce OAuthUserGenerator service and it can add OAuthUserGeneratorPlugin by extension. This service will response to generate gatein user from oauth-principal - Method OAuthUserGenerator#generateGateInUser(OAuthPrincipal principal) will do: + Find OAuthUserGeneratorPlugin by oauthProviderType, + If found plugin for this oauth provider it will delegate method OAuthUserGeneratorPlugin#generateGateInUser() + If not found, it will delegate to OAuthUtils#convertOAuthPrincipalToGateInUser() as default.
