I just upgraded to 5.0A, had some trouble with an expired CA cert (but could solve it, thanks to the forum).
Issue at the moment:
zimbra@mail:~$ zmprov -s mail.myplace2b.net
 ERROR: java.security.cert.CertificateExpiredException: NotAfter: Thu Dec 13 00:43:01 EST 2007
ERROR: zclient.IO_ERROR (invoke java.security.cert.CertificateException: Untrusted Server Certificate Chain, server: mail.myplace2b.net) (cause: javax.net.ssl.SSLHandshakeException java.security.cert.CertificateException: Untrusted Server Certificate Chain)
zmprov not working..........
I can see that there is a cert that expired on the 13th of Dec 07.... but where is it - I can not find, I created all new certs.....
thanks for your help
