RFR: 8245527: LDAP Cnannel Binding support for Java GSS/Kerberos

[Alexey Bakhtin]

Hi Max,

You are right, It is possible that algorithm name is not confirm <digest>With<encryption> format.
As soon as RFC5929 does not specify this situation I would suggest to use “SHA-256” hash instead of throwing SaslException exception.

Regards
Alexey
