Hi, I can't get my head around how the following can be consistent / right: " [domain_realm] The [domain_realm] section provides a translation from a domain name or hostname to a Kerberos realm name. The tag name can be a host name or domain name, where domain names are indicated by a prefix of a period (.). ... [domain_realm] crash.mit.edu = TEST.ATHENA.MIT.EDU < --- according to the above a host .dev.mit.edu = TEST.ATHENA.MIT.EDU < --- according to the above a domain mit.edu = ATHENA.MIT.EDU < --- according to the above a _host_ ... dev.mit.edu ... is matched by the third entry, which maps the host mit.edu and _all hosts under the domain mit.edu_ ... into the realm ATHENA.MIT.EDU. " How can a non-domain (as it doesn't start with a . ) apply to "all hosts under the domain"? Any clarification would be much appreciated. Regards Ulf Juniper Business Use Only
