Goldstein Lyor updated SSHD-366:
--------------------------------
    Attachment: 0005-Cross-reference-provided-host-keys-with-configured-s.patch

Attached is a proposed patch for the problem - it throws an SSH exception, but perhaps some other mechanism should be used (or perhaps some *IllegalStateException* would be better + logging)

> The code in _ServerSession#sendKexInit_ assumes that the provided key types from the _KeyPairProvided#getKeyTypes_ are the ones to use during the negotiation with the client. However, if there is no intersection between the 2, there is no detection or logging of the problem (even though the connection fails).
