[Samba] how to get logon.bat run with Administrator rights in domain logons?

[Urs Rau]

On win XP Pro workstations it would be so convenient if the domain logon script which is stored on 
the samba pdc could be made to run with Administrative (or System) privileges.

I know that I can interactively run another security context by choosing "run as user" but how could 
I achieve this non-interactively and domain wide whilst a "limited account" is loggin in?

Thanks for any pointers.
