Hi
I need to avoid that users, once logged in, can click on their name and access their user profile.
I see that from this page it's possible to subscribe to the groups where they aren't not enrolled.

I use MsActive directory authentication and I use custom groups to prevent uncontrolled access to pages and sites. In this case anyone may hack my security system.

I've now 2 options,
1) the easiest is to remove from the skin the control, but in this case I loose the possibility to display the user name logged in at that time.
2) try to modify user.ascx control, but I'm very new to ASPX and what I've tried I failed.

There is no a way to achieve this without a code modification? there is any parameter that can do this?
Thanks in advance
Best regards

Daniele
