+  *) Another fix for SSLv2 session ID handling: the session ID was incorrectly
+     checked on reconnect on the client side, therefore session resumption
+     could still fail with a "ssl session id is different" error. This
+     behaviour is masked when SSL_OP_ALL is used due to
+     SSL_OP_MICROSOFT_SESS_ID_BUG being set.
