Look at the methods in "AccessControl.DTML".
They allow you check various aspects of the current user.

It is very nasty, that the methods of "AccessControl.DTML"
are not exposed to Python Scripts and External Methods.
Someone did not think enough at this point...

There is an alternative way: getSecurityManager.
It is defined in "AccessContol" and returns a
"SecurityManager". It, too, allows to check various aspects
of the current user.

It can be accessed from Python Script and External Method
but not easily from DTML....
