Re: multi-server/single source authenticaton was Re: [K12OSN] Networking a new school for K12LTSP?

Thanks for your thoughts, John. I'll look for that book. I'd prefer to go all LDAP, but currently I haven't gotten the Ok to do that, primarly because it's not obvious how we would get Windows machines to authenticate via LDAP.

First a caveat: I have not (yet) tried to use AD for Linux authentication, but
I have looked into it somewhat. Since AD is primarily LDAP and Kerberos, it
should be possible, and chapter 9 of "LDAP System Administration" by Gerald
Carter (published by O'Reilly) has a pretty good step by step description of
how to go about it. You will need administrative rights to the Windows
server, since there will be some additional configuration required.

BTW anyone using LDAP should be interested in the above mentioned book, it is
a very good practical guide for many uses of LDAP. Highly recommended.
