We have a Powerbuilder 8 application with Sybase 12.5 backend. We are
trying to strengthen the application authentication by employing Kerberos
(talking to Active Directory). We know that Powerbuilder 10 works with
Kerberos, does anyone know whether Powerbuilder 8 would work too?


1) Once we are converted, how would authorization work? As we understand
it, Kerberos would take care of the authentication. However, when the db
requests get to Sybase, how does it know what authority (grants) a
particular user has (we have been told we do not need users defined in
sybase anymore)?

2) Also, if we "Kerberize" the sybase server, would all db instances in
that server be also "Kerberized"?

3) Finally, once we "kerberize" a server/database, would we be able to
logon the the server/db without going through Kerberos (via Isql, etc.)?
