Giving administrator rights to a network-known user?

[www.coffeebreak.de user]

Hello,

I´m using samba with the PDC functionality since last summer without any
problems. But now, I have to add a user, which is only known by my
samba-pdc to the rights, which has administrator-rights on the local
NT-Clients.

The problem is, that I want to use a Palm-Pilot on a NT-Client and the
installation program want to have a user with administrator rights. To
install the program as an administrator will not work, if I login
afterwards as an ordinary network-user.

Could you give me a tip, how I could handle my problem?

Thanks in advance,
Joachim.
