If you experience problems logging in to Administration Console, try restarting Tomcat.
Restart Tomcat by running this command:
/etc/init.d/novell-ac restart OR systemctl restart novell-ac.service
If this does not solve the problem, check the log file:
/opt/novell/nam/adminconsole/logs/catalina.out
Check for the following error:
Error Starting up core services. Application manager is Shutting down the Device Manager suite. Shutting down Device Manager suite.
If you see this error, check the status of eDirectory:
Run the following command:
/etc/init.d/ndsd status
If the status command returns nothing, start eDirectory manually by running the following command:
/etc/init.d/ndsd start
Restart Tomcat.
