Single Signon not working

Howdy,

For WPMU DEV SEO, the automatic links works great, however it kills my single signon with multi-site. Right now, I have a sidebar that lists the most recent domains for logged in users. They are all different, e.g. domain1.com, domain2.com, etc. When the user clicks these domains, he stays logged in. However, when we create an automatic link within a post for these same domains, the user gets logged out when he clicks.

Can you please help?

Thanks.
