It looks like LDAP can't start.
Is this a new installation of Zimbra? If so, please check your DNS setup and your hosts
file. Also be sure you don't have SELINUX running or any conflicts on port 389.
If it's not a new installation, have you made any configuration changes recently or have you attempted a Zimbra upgrade?
You don't mention what version of Zimbra you're using and on what OS. That might be helpful to know. |
