Debugging in Dynamics AX 2012 as a non-admin Role

To access breakpoints as a limited user:
1. open dynamics as admin
2. add yourself to your favorite role (in addition to admin)
3. shift control w to open a workspace.
4. insert a break point into a well know x++ class that the role accesses.
5. create a new job
6. insert this:
static void NonAdmin(Args _args)
{

securityutil::sysadminmode(false);
}
7. run job
8. control w to open regular workspace (or open it from the menus, sometimes its sticky)
9. Open the form/class via navigation

observe that you can now stop in debugger as "limited" user
