I'm not that acquainted with WordPress.

I want something I'm able to setup to make use of Single Sign Up with my existing application (Multiple accounts with multiple customers).

I have to host this on a single server and display your blog on the remote server and have the ability to theme it there..

Can WordPress do that with no troublel .? The only real SSO stuff I've found for Wordpress is by using other major programs, like Facebook.

Otherwise can there be another, simpler method apart from writing my very own?
