Oracle, Kerberos and Cross Realm

[Sam Hartman]

Unless it has changed significantly, Oracle's Kerberos--even on
Windows-- wants to use a MIT style version 3 ticket file.

You want to grab Kerberos For Windows, set up your krb5.ini to include
CCACHE_type=3 in the libdefaults section.

Then, set the KRB5CCNAME environment variable to some path--not to
FILE:some-path as is typically used.

Then run the ms2mit executable included in Kerberos For Windows.

If I'm confused and sqlplus now supports native Windows Kerberos this
can all be much simpler.
