Connection refused after stopping and restarting the server

Sorry, might be just a documentation problem but I have not been able to find it in the doc.

I have installed apacheds on a virtual private server running ubuntu using the following steps :
`dpkg -i ` the downloaded debian installer
started the service : `service apacheds-2.0.0-M15-default start`

I am then able to connect from a remote pc with directory studio.
I then do following configuration changes to change the default example partition :

edit the ads-partitionId=example under ou=config,ads-directoryServiceId=default, ou=partition

change the ads-partitionid to dynamease
change the ads-partitionsuffix to dc=dynamease,dc=net
change the ads-contextentry to reflect the 2 above changes.

I did that about 2 months ago. It worked pretty fine and my application was able to access and work with ApacheDS properly.

This morning I wanted to reboot my server. Despite several trials of service stop/start/restart, I have been unable to open any connection to the directory server.

Thanks in advance,
Yves
