Re: Out of ideas when troubleshooting TLS negotiation failure

It did make me wonder! The failure right after "write client key exchange A" does seem to correlate with my wireshark capture (client sends a "decrypt error" (TLS alert code 51) to the ldap server after receiving the certificate).

The actual error from ldap_simple_bind_s is:
error:0D0C5006:asn1 encoding routines:ASN1_item_verify:EVP lib

This is a FreeBSD 10.2 system, which uses openssl 1.0.1p. Both smbd and my test should be linked to the same ldap and ssl libraries - here's ldd output:
