Setting up a linux server to authenticate windows users
I'm not too sure if this is the place for this thread.
I was wondering if anyone could help, I have recently set up a Ubuntu 6.10 server using an old PC (700MHz, 64MB RAM, 4GB HDD), the distribution is in text mode due to the lack of resources. I am looking to centralise most services on a home network onto this server. I wanted to know if there was any way to authenticate both windows and linux users from this machine. I can install and set up NIS on it for Linux users, and the machine doesn't have enough power to run a windows server in a virtual machine. Can samba authenticate windows users or can windows machines login to something other than active directory.
Any help would be appreciated.
