[krbdev.mit.edu #1259] [Richard Hanschu <richardh@examen.com>] Bug#169014: krb5-kdc no longer interops with Solaris SEAM

[Sam Hartman via RT]

The following Debian bug report describes an interop problem between
Solaris and MIT Kerberos 1.2.6 or greater.  The patch under discussion
is the patch we introduced in 1.2.6 to send etype_info.

Apparently we send etype_info corresponding to etypes that the client
didn't request and thus doesn't understand.

This seems to be fairly close to a violation of the extensibility
guidelines in the Kerberos protocol spec.
