Zimbra SSL Certificate expiry downs LDAP

zimbra shows error when i tried to start.

Unable to determine enabled services from ldap.

Unable to determine enabled services. Cache is out of date or doesn't exist.

The reason was i installed SSL with a validity of 365 year ago and forgot to regenerate.
LDAP doesnt start with a expired SSL.

Follow steps below and generate SSL for 3650 days (ten long years)

## Regenerate SSL certificate and deploy as given below

su - zimbra -c 'zmcontrol stop'
rm -rf /opt/zimbra/ssl/*
rm -rf /opt/zimbra/ssl/.rnd
