Many thanks for the hint. :-)

Are there different editions of Kaufman-Perlman-Speciner ?

My edition of 1995 has two entries for principal in the index:

- Page 129: "A principal is anything or anyone participating 
  in cryptographically protected communication."

- Page 266: "each user and each resource that will be using 
  Kerberos."



Which edition is yours?

regards
Hadmut
