I have configured dovecot to use Client certificate authentication. I have used CA.pl (openssl wrapper) to create CA cert and sign client and server certs with that.(no certificate chain, CA cert is trusted in client) I have set the certificate as CA certificate in dovecot for client auth. Dovecot correctly asks IceDove for certificates but after clicking OK, It fails with error "Client didn't present valid SSL certificate."
Using openssl to manually test IMAP connection also results in this error.
dovecot config: https://gist.github.com/Xcess/71f7eeeda0a270b252f1de5d7308c0e2
I have tried certificate with CN=user1 and CNfirstname.lastname@example.org. both failed. Also set common-name to be username in dovecot conf...no difference.
I don't know what to do as this is all stated in manuals and seems pretty simple and straightforward. But it fails.
