Kolab Free-Busy via Https

[Josh Janszen]

All,

I am trying to get Kolab free-busy working via https:// but nothing 
seems to be working, I tried via http:// also and it doesn't seem to 
work either. When looking through the logs it shows;

kolab-freebusyd(22369) KIMAP::SessionThread::reconnect: 
connectToHostEncrypted "localhost" 993
(19:45:04) findkolabfoldersjob.cpp(111):        "GetMetaData failed, 
server replied: A000011 BAD Missing arguments $
kolab-freebusyd(22369) KTcpSocket::showSslErrors: "The host name did not 
match any of the valid hosts for this cert$
kolab-freebusyd(22369) KTcpSocket::showSslErrors: "The certificate is 
self-signed, and untrusted"

Do I have to have a signed certificate for this to work?

Thanks,
Josh
