Thanks for info.
Unfortunately,we have v10.
Though v10 also has same parameter, it doesn't work and not formally supported.
Additionally, according to the help document, this setting affects every user group not only a specific group.
What I want to do is that we prepare the account who can only download the documents and whose menu has only 'Download Center'.
Report and Change Password menus are not necessary.
We'd like to use this account to let our customer download the necessary documents to get our backup service using Simpana.
The customer also experience Simpana interface in parallel.
If no one has an idea, we'll give up this way...
