where there are that datas??? Yes I know that there are located into I had a little trouble understanding your e-mail message, but I will answer what I think you are asking. When I log into an Athena Workstation a line is created for me in the passwd file. The contents of this line are obtained using Hesiod. Hesiod is a general purpose naming system. It is layered on top of the Internet-standard Domain Name System (DNS) using the Berkeley Internet Name Daemon (BIND). I can send you a little more information personally, if you are interested. Zephyr is a real-time messaging service, and is only started when a user logs in, for convenience. I believe you'll find that the principal.pag file you are referring to is only on the kerberos server, not the client workstations. BTW: Hesiod and Zephyr are registered trademarks of MIT.
