Update user groups/accesses

[meLeti245]

We have access: "Public", "Register", "Premium" and groups "Public", "Register", "Premium". Access name = Group name.

We have material: "New Article", that can be viewed only "Premium".

We have user "Foo", he have access "Register" only. He not see "New Article".

Now, we give "Foo" new group "Premium" (and, accordingly, a new access "Premium"). But, "Foo" does not see "New Article". If "Foo" logout and again login, he can see.

How I can reset (cache/session/cookie?) info about groups/accesses for "Foo" user? Need he could immediately see the materials, after the appointment of the new groups.

To my knowledge this is not possible. The access rights are loaded during the login.
Even if you delete/reset the session for a user, he would be kicked out and have to log in again.
