You speak as if you have E-Smith mosix running or at least LDAP
authentication working via E-Smith....is any of this true?  I am a big
E-Smith/SME aficionado....have several servers....I've always wanted to
have E-Smith be the central point of authentication for K12LTSP and
Windows.   I can do this with my current Samba/LDAP setup, but an E-Smith
set up would rock!  Fill me in if you have this running.
