samba - Jun 2003 - Local authentication or synchronization with win2000/win2003 serv ers.

Hi,
I have a win2000 or win2003 server as PDC, on another site i have a samba
server with samba 3.0.0 alpha2.4
I am familiar with winbind and that's not what i need, i saw the
documentation about ADS support (with the MKS AD4Unix) but then still you
have your authentication on your windows server.
This costs data over the lines and if the line breaks, then nobody at the
site where the linux server is with samba can work further.
How can i solve this ?
Or is it possible with ADS support ?
OpenLDAP ? But this is not supported by microsoft.

Help plz, i just need the idea behind it, the rest i can find by myself.

GreetZ!
