Hi m at ainc.be

we had also problems with SSL and calendarserver 3 under Wheezy. It all 
was solved when we added the server certificate also the the chain 
  - SSLCertificate => single server cert
  - SSLAuthorityChain => server cert,  issuing/intermediate cert(s), 
root cert (with "cat >> chain-file")

Give it a try, our SSL works fine now, without any cipher settings

best regards, Radim
