On every back-end server, log in as an administrator with permission to change the configuration.
Change to the /etc/opt/SUNWics5/cal/config directory.
Save your old ics.conf file by copying and renaming it.
Edit the ics.conf parameters as shown in the following table:
Description
Set this parameter to "no".
There is no need for HTTP on a back-end server.
Enable the administration service (csadmind) by setting the parameter to "yes", which is the default.
If this machine is a back-end only machine, set to "local". If this machine is both a front-end and a back-end, set to "directory".
Set this parameter to "no".
There is no need for a plug-in on a back-end server.
Enable DWP by setting this parameter to "yes"
The default port is “59979”. This port number must be the same for all front-end and back-end servers.
This is a multi-valued parameter. Create one ics.confparameter for each back-end server in your Calendar Server deployment. The value of this parameter is the back-end server hostname. The server name must be fully qualified and be resolvable by your Domain Name Service (DNS) into a valid IP address. The server name must be identical and fully qualified in both the parameter name and the value.
For example:
caldb.dwp.server.calendar1.sesta.com="calendar1.sesta.com"
caldb.dwp.server.calendar2.sesta.com="calendar2.sesta.com"
Set the default DWP server name used by the system if the user or resource LDAP entry does not have an icsDWPHost attribute. The server name must be fully qualified and be resolvable by your DNS.
For example:
caldb.dwp.sever.default="calendar1.sesta.com"
The hostname where the Directory Server is installed. The default is "localhost".
The hostname where the LDAP user preferences are stored. If you do not keep the user preferences in a separate LDAP host, then it should be set to the same value as local.authldaphost.
To enable ENS (enpd) for this back-end server, set this parameter to "yes".
Server alarms must be enabled ("1") on the back-end servers.
Save the file as ics.conf.
Restart Calendar Server.
