0. I did the ./clean-all, build-ca and build-dh, just to be safe: started clean.
1. I recreated the client key without a password.
2. I adapted and applied the following commands:
"openssl rsa -in client.key -out client.key"
"openssl rsa -in client.3des.key -out client.3des.key"
3. I recreated client.conf.
Rebooted. Still asks for a Private Key Password of my client.

I really don't know where to go from here. Am I the only one with this problem?
