I should add, the easiest is to use pgina with just the ldap plugin,  
turn on plain text passwords on the clients, and write a bat file to  
map drives to a samba share with pam krb5/pam afs session stack. You  
can get identical ssid's acrossed all the samba servers if you use  
identical windows hostnames. You can use pam_ldap or nss ldap to get  
your usernames to the unix user accts.(AD doesnt let you do that.) (It  
can be the same server as your ldap auth server.)

We set it up to run out of inetd so it autorestarts. Windows can cache  
the creds and auto reconnect if you need to replace the machine and  
firewall off a lot of the chatter the protocol does. But you can  
probably run it as a stand alone server.

We have/had this running with stripped down solaris 8 sparc  
400mhz/128M of ram reliably for years (compiled a few things out of  
samba as well). If you want a small cheap machine, I'm guessing a  
guruplug (which is cheap and only uses 5-10w of power max. and < .5w  
idle and has esata) would give similar performance, but I haven't  
tested it yet.

On a side note, the ARM Cortex-a15's 2.5ghz quad cores should come out  
in less then a year and there are a couple of companies interested in  
pushing these out as low E servers.
