Application Server and KDC share some information like Service Tktkey?

[Surendra Babu A]

Hi,

Thank you for the reply.

1. Windows Exchange server (SMTP server running with that) can be used for
Kerberos Server Authentication?

2. I could not get proper response from the SMTP server when I sedn the
service tkt+authenitcator information to the SMTP server.

Let me tell you clearly.

I am using Microsoft 2000 exchange server. It has SMTP service. I am able to
to do User Authentication but not Server Authentication.

For Server Authentication, I am sending the SMTP service tkt + Authe
nticator information to the SMTP server. The SMTP server is sedning the
response. But myKDC is not able to decode the response.

That means, some thing to be done (keytab file generation/etc) to be at done
at SMTP server side???

Please let me know your thoughts.

Happy Christmas.

Regards,
-Surendra
