Comment 1 for bug 991342

DC++ follows the spec in this regard; this should be discussed with ADC maintainers to decide whether taking the cert chain into account is indeed necessary.
rev 34 of ADC might be relevant: <http://adc.svn.sourceforge.net/viewvc/adc/trunk/ADC-EXT.txt?r1=34&r2=33&pathrev=34>

is this really a security issue? if 2 peers disagree on their KEYP, the worse that could happen is a failure to establish the connection. i fail to see how a third party could exploit this divergence to "sneak a cert into the chain" while keeping the KEYP intact.
