[stunnel-users] Interoperability problems with .net client software

Looks like your client is not presenting the certificate to the stunnel server. Maybe because it does not trust the server certificate? Did you import your stunnel server cert into windows certificate store?

Hi all,

I'm using stunnel 4.53 under Linux to secure a service. There are two 
different clients connecting to this service: My own client, also Linux 
based and using libcurl and another (third party!) client being 
developed using Microsoft .net stuff.

Of course with my own client all works well. But we are not able to get 
the Microsoft client running. stunnel keeps on telling:

SSL_accept: 140890C7: error:140890C7:SSL 
routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate

We have tried diffierent things... I will outline them here if you think 
it is helpful (in short: tried using certificates generated on the 
Microsoft side, then tried using certificates created on the Linux side).
If "verify" ist set to 0 or 1 it works (of course) but with a higher 
value the above message is logged.

Are there any known pitfalls, problems or whatsoever when using stunnel 
with a .net client?
Any advice would be appreciated!

Regards,
Gregor
