Hi, I'm indirectly using OpenSSL through Net::SSLeay¹, which I use through AnyEvent::TLS². AnyEvent::TLS provides the means to define a custom verification mechanism by setting verify_cb³. Here's an example (keys included):
http://paste.scsys.co.uk/159837 If the custom verification callback decides a peer is bad, it shall return 0 and return 1 otherwise. If 0 is returned, this warning is produced: ssl3_get_client_certificate: no certificate returned It's only a warning which does not seem to impair functionality; no warning is printed if 1 is returned. I've already asked on the AnyEvent mailing list⁴, but the author of AnyEvent::TLS couldn't really nail it down either. Can you help me? Why is this warning printed and what could be done to eliminate the problem? TIA, Tobias ¹ http://search.cpan.org/~mikem/Net-SSLeay-1.42/lib/Net/SSLeay.pm ² http://search.cpan.org/~mlehmann/AnyEvent-6.1/lib/AnyEvent/TLS.pm which I use through AnyEvent::MPRPC, but that shouldn't matter :-) ³ http://search.cpan.org/~mlehmann/AnyEvent-6.1/lib/AnyEvent/TLS.pm#verify_cb ⁴ http://lists.schmorp.de/pipermail/anyevent/2011q4/000203.html
