My quite limited understanding of the behaviour of SSL client
authentication may potentially help a little:
You initially send a certificate signing request to the
admin/owner of the server (signed with your private key); when
you receive the certificate reply (signed with their private
key), you can build a chain of trust between you and the server,
your keystore will look like:
Entry type: PrivateKeyEntry
Certificate chain length: 2
Certificate[1]:
Owner: <you>
Issuer: <server>
Certificate[2]:
Owner: <server>
Issuer: <server>
Then at the SSL handshake time, first the server presents his
certificate, second it asks for a client certificate, at that
time you are able to present the certificate belonging to the
chain of trust containing the server certificate on top.
