Multi Site, Not adding user to site after first login.

Okay, Ill try and explain this one. I am running a WordPress Multisite instants and using this plugin and have checked the setting “Create WordPress user for authenticated LDAP login with appropriate roles.”.

When user A visits site A for the first time and logins in an account is created and the user is added to site A.

If user A visits site B and logins for the first time they are granted access to site B but they are not added to the user list of site B, and have no access to the dashboard.

Is this normal, or am I missing a configuration step.
