I have an application which is completely written in Java with Spring framework. Right now I need to integrate this application with some other application that is written on WordPress. I need to seamlessly support the same user database for both of these application. I understand that I need some kind of Single-Sign On(SSO) that is supported of Spring(can be used with Spring Security) and WordPress.
Right now Spring application manages users via own Spring OAuth2 Authorization server. Is it possible to use this server in a separate WordPress application ?
Could you please recommend some SSO solution for this case ?
UPDATED
Maybe it is possible to use CAS Jasig for this purpose ? Do we have support of Jasig for WP and Spring ?
If so I have an additional question about Jasig CAS architecture – where users for WP and Spring MVC applications must be stored ? I mean it is a single store(for example the same mysql database) or it can(must) be a different stores for each application ?
