    Default Can't start Zimbra MTA

    Dear experts,
    I have two server: one for mailbox server and one for MTA Server. The system is running ok but today, I see that I can't start Zimbra on MTA Server. Each time I try to start, Zimbra said that:
    Unable to determine enabled services from ldap.
    Unable to determine enabled services. Cache is out of date or doesn't exist."

    I have checked everything about hosts file, resolv.conf file, dns, ... and there are no problem. When I try to update key by zmupdateauthkeys on MTA server, I see the following error: "ERROR: service.FAILURE (system failure: ZimbraLdapContext) (cause: PKIX path validation failed: signature check failed)".
    Please help me to resolve it.

    Thank you so much!

    You should try a search before posting a question, search the forums for the words 'PKIX path validation failed'.

    I had similler problem my certifacte was expired. It happend exactly after 1 year. Try to recreate certs.

    I did following thing as root

    chown -R zimbra:zimbra /opt/zimbra

    /opt/zimbra/libexec/zmfixperms -verbose

    /opt/zimbra/bin/zmcertmgr createca -new
    /opt/zimbra/bin/zmcertmgr createcrt -new -days 365
    /opt/zimbra/bin/zmcertmgr deploycrt self
    /opt/zimbra/bin/zmcertmgr deployca

    Above command might give below error.
    ** Saving global config key zimbraCertAuthorityCertSelfSigned...failed.
    ** Saving global config key zimbraCertAuthorityKeySelfSigned...failed.

    Restart the services:

    su - zimbra -c "zmcontrol stop"
    su - zimbra -c "zmcontrol start"

    and reenter the command to deploy the certificate on ldap: this time it should not give any error

    /opt/zimbra/bin/zmcertmgr deploycrt self
    /opt/zimbra/bin/zmcertmgr deployca
