Implementing Kereberos Server's.
If we implement Kereberos and start the Kerberos server
does the TSS top secret address space/task have to be stopped and started?
No you do not have to recycle the Top Secret address space to coordinate any implementation of Kerberos.
There are various objects that need to be defined to Top Secret that support the requests that will come from the server.
This is all documented in the Cookbook for r15 and in the Using section of the online documentation for r16.
