Hello everyone!

I installed Zimbra 6 and I want to install an SSL certificate GANDI; I then followed the instructions correctly on the page Installing a Gandi Commercial Certificate on ZCS 5.0.x and 6.0 - Zimbra :: Wiki . x.
I had no error. Now, when I tried to restart the Zimbra server is where I realize that there are some services that do not work.

antispam Running
        Running antivirus
        ldap Running
        logger Stopped
                zmlogswatchctl is not running
        Mailbox Stopped
                zmmailboxdctl is not running.
        mta Running
        snmp Running
        spell Running
        Running stats
When I tried restarting everything, I have the following error:

HTML Code:
Unable To determine enabled services from ldap.
Enabled services read from cache. Service list may be inaccurate.
        Starting logger ... Failed.
Starting logswatch ... ERROR: service.FAILURE (system failure: ZimbraLdapContext) (cause: javax.net.ssl.SSLHandshakeException sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target)
