FYI - I have now tested with 1.0.1 beta 2 of openssl (again complied on 
powerppc/linux) as well and found the same behavior.  I also tested against IIS 
on Windows 7 64bit as the server with the same behavior.  Maybe that will help 
with the search for a suitable test server.



Test used

$ openssl s_client -connect stk-pc.a51.lab:443 -cert /config/lighttpd/ssl.pem 
-CAfile /user/http_calist.pem -no_tls1_2 -no_tls1_1

Works



But

[C90-A:~] $ openssl s_client -connect stk-pc.a51.lab:443 -cert 
/config/lighttpd/ssl.pem -CAfile /user/http_calist.pem

Does not and fails with a error 104 - which is IIS doing a hard reset on the 
connection and reports bad_mac_record in window's schannel provider.



If you still can not find a suitable test server, I may be able to arrange one 
on a public IP, but that would have to be something done as a coordinated test 
and I would have to take that off-list to discuss.



Thx

Thanks, that seems OK.

The public test server I normally access is down atm. Does anyone know

of a public IIS test server requiring client authentication?
