In the process of troubleshooting the LDAP user problems I was experiencing I found that by default the logging of info and debug messages is turned off by default for the OEM jrun install that is part of Contribute Publishing Server 3.11.
In order to enable these logging levels you have to edit the sevrer configuration xml file. This file should be located in the configuration directory of your jrun4 server’s WEB-INF folder.
The name of the file is: ckm.xml
Open this file in your favorite editor and look for the following section:
/usr/Macromedia_CPS/logs/out.log /usr/Macromedia_CPS/logs/err.log true true true
By default the logger is only set to show error messages. This section also shows the location of the error logs and the output logs.
Note, that enabling this you will get larger log files, since this will log all connections to the LDAP server by the Contribute client(s) that you have installed. You may find it necessary to open the admin console and set a max log file size to control this.
