User Restriction in ENSEMBLE

HI friends i develop a application in ENSEMBLE [2009], in that i restrict some user to access 开发者_运维问答all links except "Ensemble Management Portal" i done this by changing roles for that particular user as Home->securitymanagement->Users->Editusers->roles. But when i logged in in to the system managenet portal and change the namespace it's logged out , Again i try to login means i got the Error Access Denied , Please help me to find the solution Thansk in advance

I think you just don't have enough privileges to access specific namespace. Just remove $NAMESPACE=something from URL when you try to login again.
