Lion Server webservice

Hi, this is my first post in this forum. First of all, sorry for my bad englisch, i´m from germany!

And now my problem: the webservice on my lion server does not work.
After the installation it worked, after that i wanted to enable SSL, so i set a self-generated root certificate for the webservice.

And now i get this errors in the apache error_log:

[error] SSL Library Error: 218734605 error:0D09A00D:asn1 encoding routines:d2i_PrivateKey:ASN1 lib
[Tue Aug 02 11:07:24 2011] [error] Init: Pass phrase incorrect

If i remove the certificate from the webservice, it also doesn´t work.

I think it´s a little bit strange, because with certificate the webservice called a HTTP site, without certificate a HTTPS site.

Can anyone explain this?
