Login is possible if Enterprise Manager is configured to use file-based authentication (users.xml)

Does not affect Enterprise Manager running on other platforms such as Linux or Windows


APM 10.5.1 running on AIXConfigured to use EEM for authentication/authorization, EEM could be running on any platform.


The Enterprise Manager is an OSGi application which changes the way that classes are loaded and the required 3rd party library cannot be found.

Suspicion is use of IBM JRE which is delivered with the Enterprise Manager running on AIX is having an impact on class loading.


We can add a property to allow all code to be loaded by the main JVM class loader so that the class is found.

2) Find the property

3) Append the following value


4) Restart the Enterprise Manager
