TM1Web portlet in C8

[Toto]

Hello,

I have to TM1-portlets in C8 on one page. When I logoff from C8 and login with a different user it seems that one portlet still has the old user. After restarting the TM1-Server and login with the new user everything is fine. Did you experience this as well? What could help here?

Thanks a lot,

Toto

Additional info:
When I use TM1Web without portlets and log out the login-sreen appears. Now when I press the button "login" I would expect to be asked for my password, instead I am automatically logged in again. Is this why my login is still the old one in the C8-portlet? How can I change this?

Thanks a lot,

Toto
