I have been running Zimbra Release 7.1.4_GA_2555.UBUNTU10_64 UBUNTU10_64 FOSS edition for just over a year now without any issues. Since yesterday the users complained that they cannot access the serve. When we started to investigate this morning, we found that the certificates have expired. With the help on the forum we have tried to create new certificates. Unfortunately it seems as if the server does not want to start up again.

We get the following message:
root@mail:/opt/zimbra# service zimbra start
Host localhost
Unable to determine enabled services from ldap.
Unable to determine enabled services. Cache is out of date or doesn't exist.

I have spent hours on the forum today to search for ways to fix this. I can confirm that the DNS is setup correctly as this has been running for over a year.

Could someone please help us to resolve this issue?
