[keycloak-user] spring-social-keycloak

Hi I have more than 20 application that launch in private cloud with spring security framework,after some search i decide to create IAM (SSO) for these application after search in google ,i found Keycloak project that one of best project for do that . all my apps in organization have own user management and do not want to change that . my idea is to launch Keycloak in our organization and each user in organization have account in Keycloak,but both user have same email . when user want to login in app can login with app user and Keycloak user .in this way Keycloak is like google for Github or Facebook that each user can login with Github user or google account. after read Keycloak documentation i do not see library that make this for combining local authentication and keycloak authentication.i want when kecloak authentication do success i setAuthentication with app authentication . after some google i found spring social project and i decide to create spring-social-keycloak .but i do not see good documentation for request response . or any sample for curl that i know how can use that in my project https://github.com/azizkhani/spring-social-keycloak it is my idea is correct? is any sample that show curl for authorization code flow and get user info ? is keycloak is active in gitter.im for online question ?
