The server log contains Quartz errors
Make sure to synchronize the time on all computers used in the LDD system before installing LDD components.
If the time is not synchronized, then do the following:
1 Uninstall all components.
2 Synchronize the time on all computers using an NTP server.
3 Reinstall all components.
Kerberos authentication is not working
Make sure the date and time are correct and synchronized on the printer, LDD server, and KDC sever.
To log Kerberos debug messages from the Java Virtual Machine on each server, add the line
‑Dsun.security.krb5.debug=true to the Windows registry key HKEY_LOCAL_MACHINE\SOFTWARE\Apache
Software Foundation\Procrun 2.0\Tomcat5\Parameters\Java\Options.
Note: Do not delete the existing contents of the registry key.
Warning—Potential Damage: Incorrectly editing the Windows registry may damage your Windows installation and
result in an unusable system. Make sure you understand how to make the required changes. We recommend
backing up the registry before making any changes.
Debug messages are logged in the file stdout_xxxxxxxx.log in the \Lexmark\Solutions\tomcat\logs\ folder where the
LDD server is installed.
