When I try to install zimbra on a DEBIAN 3.1 host in VMware 5.5.1, I get the following message and zimbr does not start :

Adding test.ccdmd.qc.ca to zimbraMailHostool in default COS...ERROR: service.FAILURE (system failure: getDirectContext) (cause: javax.naming.ComunicationException test.ccdmd.qc.ca:389) ERROR: service:FAILURE (system failure: getDirectContext) (cause: javax.naming.CommunicationException test.ccdmd.qc.ca:389)
