HTTP Status 503 - This application is not currently available - when trying to access iManager

Novell eDirectory 8.8 for Linux
Novell iManager
Novell Tomcat
Novell eDirectory
Novell Open Enterprise Server 2 (OES 2) Linux


* After reinstalling iManager, cannot access iManager, but iMonitor works fine
* After following KB 7005833, iManager still does not work.
* After reinstalling novell-tomcat5, iManager does not work

All the above give me the error "HTTP Status 503 - This application is not currently available" when access the iManager page

The output of /var/opt/novell/tomcat5/logs/catalina.out, shows the below error message:

May 19, 2010 14:11:01 PM org.apache.catalina.session.ManagerBase getDigest
SEVERE: Cannot find message associated with key managerBase.digest MD5 MessageDigest not availabl


If iManager had been previously working, there would have been a valid file. Search for the file under security.backup and restore it to the security folder. The path of the security folder varies, depending on the java version on your machine. Example is as follows


In case, the you do not have a backup folder for security and the contents of the file is empty, add the following lines to the file. If the file is not empty make sure all of these lines are present and un-commented. Also note that the order of the lines in the file is relevant.

Save the file and restart novell-tomcat5 (rcnovell-tomcat5 restart). Now iManager should work.

The version of java that iManager is using is not necessarily the only version or the default version of java on the server. Make sure you edit the file for the version of java that iManager is using.
