I was attempting to install a SSL cert using the web interface. I rebooted the server and now the services will not start. I performed several things that I found on the internet such as...

/opt/zimbra/bin/zmcertmgr createca -new
/opt/zimbra/bin/zmcertmgr deployca
/opt/zimbra/bin/zmcertmgr deploycrt self -new

I get this...
[root@mail zimbra]# /opt/zimbra/bin/zmcertmgr createca -new
** Creating /opt/zimbra/ssl/zimbra/ca/zmssl.cnf...done
** Creating CA private key /opt/zimbra/ssl/zimbra/ca/ca.key...done.
** Creating CA cert /opt/zimbra/ssl/zimbra/ca/ca.pem...done.
[root@mail zimbra]# /opt/zimbra/bin/zmcertmgr deployca
** Importing CA /opt/zimbra/ssl/zimbra/ca/ca.pem into CACERTS...done.
** Saving global config key zimbraCertAuthorityCertSelfSigned...failed.
** Saving global config key zimbraCertAuthorityKeySelfSigned...failed.
** Copying CA to /opt/zimbra/conf/ca...done.

Now, when I try to start the services i get this...
[zimbra@mail ~]$ zmcontrol start
Host mail.domain.com
Unable to determine enabled services from ldap.
Unable to determine enabled services. Cache is out of date or doesn't exist.

I have users that need to get to their email...
