No worries! I even saw your second mail that explained your first
patched did only solve half the problem during I browsed the mailing
list search hits for ssl. But my brain was not able to bring both
mails into relation. :)

Thanks for the warning. We very likely won't need ssl distribution in
production until R12 comes out. I just tried to test it to be prepared
for the time we will need it. And I think we can rely on our Erlang
maintainers that they will fix ssl in the next release.

Another maybe quite dangerous problem with the current SSL implementation:
Even if I trun on
-ssl_dist_opt verify 1 depth 1
server side and use completely bogus self-signed certificates on the
client, Erlang gladly greets me with a prompt. In my understanding if
I turn on verify, SSL should verify the certificates, realize that no
chain of trust can be built and send me to hell!?
Apologies up-front if this behaviour is normal and I misunderstood
something completely!

Since it's probably questionable whether tiny Michael is allowed to
criticize people who dedicate a tremendous amount of time to build
such a terrific system as Erlang, I hope the following is rather
interpreted as fair comment: Please test cryptography packages before
letting them out into the wild!
