Sun Ray is... a very different architecture. Merged authentication has
been available for decades now, with NIS, Kerberos, LDAP, or the
entwined Kerberos/LDAP mix that AD and therefore Samba use. Yeah, it's
handy, but creating home directories on first login is actually a
Linux PAM issue, not  a Samba/AD issue per se.

Hmm. Sun Ray is hampered by the attempt to run X servers on a thin
client. X is.... bandwidth and resource greedy, which is one reason
that graphical "thin clients" hae never worked well for UNIX and Linux

Surprisingly, laptops running a simple Linux (such as Scientific
Linux) and running  the www.nomachine.com "NX" software provide
surprisingly good and manageable and efficient graphical access to
centralized servers.

That's..... perverse. Possibly efficient and effective! But perverse.
Running one's own subdomain, including using Samba oon a Scientific
Linux box, is often the only way to get sane internal
DNS/DHCP/CIFS/LDAP in a Windows environment.
