You're not missing anything.  I've experienced a similar issue.  While 
verify = 4 generally works well in most cases and will ignore the CA
chain, I've encountered a few isolated incidences in which I've had to 
append or "chain" the server certificate with the certificate of the CA. 
Give it a shot and see if it resolves your issue.
