 Results from Kerberos Interop session:

  - 64-bit Windows compatibility

  - correct uninitialized variables

  - work without kerberos 4 libraries including krb524

  - add a mechanism to add and remove identities from
    the options dialog.   This allows a configuration
    to be specified using a separate file based ccache
    for each identity

  - work without availability of ccapi

  - force a renew of credentials on startup to support
    the case when MSLSA is the only credential cache
