Hi, all
     I found that JndiLoginModule will associate a UnixPrincipal,
UnixNumericUserPrincipal, and the relevant UnixNumericGroupPrincipals
with the subject if logging succeeds no matter whether it is a windows
client or unix client.

    So I will move UnixPrincipal related classes from current Unix
specified directory to common directory if no one objects.


Good luck!
Leo
