SAML SingleSignOn for JIRA, Confluence and Bitbucket has been tested in Datacenter environments and is fully supported.
There are some known issues in the Datacenter editions with plugins in general, where in rare cases there can be Issues after a plugin has been disabled & re-enabled or upgraded.
These issues can also affect our plugin, hence we generally recommend restarting the cluster nodes after the plugin has been upgraded or disabled and re-enabled. If you don't want to do that please watch out for error messages like those shown below:
Exceptions like this could occur in the logs of the other cluster nodes when saving the configuration:
2017-09-07 12:44:48,067 ClusterMessageHandlerServiceThread:thread-1 ERROR [c.a.jira.cluster.OfBizMessageHandlerService] There was a problem handling a cluster message org.eclipse.gemini.blueprint.service.importer.ServiceProxyDestroyedException: service proxy has been destroyed at org.eclipse.gemini.blueprint.service.importer.support.internal.aop.ServiceDynamicInterceptor$ServiceLookUpCallback.doWithRetry(ServiceDynamicInterceptor.java:102) at org.eclipse.gemini.blueprint.service.importer.support.internal.support.RetryTemplate.execute(RetryTemplate.java:81) [...]
In this case, changes in the plugin's configuration are not propagated correctly.
Exceptions like this could occur on any cluster node after re-enabling the plugin:

These problems seem to be caused by the OSGI-framework where the service-proxy-components are not torn down and reloaded correctly. Restarting the node solves this.
