Kerberos beyond one organisation
I have startet to study Network Security, but don't got the books I have ordered.
Now I have to send in some answers to chapter 1 and 2 of the book "Design Network Security" can anybody help me out?
The question is:
"Can kerberos succesfully be used beyond one organisation? Hint: It can be problems with this kind of sollution"
I have read all I can find about kerberos, but can't find the answer for this question.
