Agreed.  Needs only documentation.  (I'm working on it.)

Can username/password be NULL?  

The word "Kerberos" does not appear in the UG.  That's because I have no
direct experience with it and no one who understands it has documented it.

I myself would like to use Kerberos for FreeTDS on RHEL.  Any advice on
what to tell my Linux admin and my MSSQL admin, to make sure FreeTDS will
be able to connect?

I don't understand why "isql.exe -E" and "bcp.exe -T" exist.  ISTM if the
user doesn't provide -U and -P then the library should attempt a domain
login for $LOGNAME.
