MIT kadmin not using DNS

[Richard E. Silverman]

A (I hope) quick question: I see claims in various places (including the
O'Reilly Kerberos book), that kadmin will use DNS SRV records to locate the
admin server -- but it doesn't seem to.  The Solaris derivative *does* do
this, and works for us, but running MIT kadmin in the same environment
requires the admin_server parameter in krb5.conf.

Any ideas?
