Package interferes with session sharing in some way

I have systems in subdomains where I share login between them, after installing the package, the system that was installed stopped recognizing the login of the other systems.

If I logged in on other systems, I should log in again on this one.
But in some ways, they use the same cookie as logging out on any other system, logging out of it (if you have redone the login)

It is a very good package, I really liked the idea and the ease, but I had to choose to remove it since the need to re login to a system was impacting the user experience.

If you have any idea what this is affecting, I would love to wait for a possible fix, I am interested to keep using the package.
