What this block usually indicates is that either the cache manager is not initialized, or the cache instance it's trying to retrieve is not initialized:

So, basically yes. The passwords are getting cached. We are just having issues getting them replicated across the nodes. It is looking like we will have to start looking for alternative methods since ehcache doesn't look like it's going to work for using clearPass with uportal. I am sending this over to the CAS community as well.

Also is there any more to that stack trace? It seems like it might be missing a "Caused By:" or two. -Eric On 06/20/2013 02:21 PM, Young III, Russell Alonzo wrote: One thing that I just noticed is that CAS client v3.2.1 is using v2.2.0 of ehcache and uportal 4 is using 2.6.5.

I have the following in the uportal-war web.xml under the CAS validate filter. <init-param> <param-name>proxyGrantingTicketStorageClass</param-name> <param-value>org.jasig.cas.client.proxy.EhcacheBackedProxyGrantingTicketSt orageImpl</param-value> </init-param> We are using the Cas20ProxyRecievingTicketValidationFilter. uPortal already has a Cache Manager setup in it's src/main/resources/properties/ehcache.xml using Jgroups. I added the following to that file. <cache name="org.jasig.cas.client.proxy.EhcacheBackedProxyGrantingTicketStorageIm pl.cache" eternal="false"maxElementsInMemory="1000"overflowToDisk="false" diskPersistent="false"timeToIdleSeconds="0"timeToLiveSeconds="300" memoryStoreEvictionPolicy="LRU"statistics="true"/> I tried this with the name being both with and without the ".cache". Either way the CacheManage in the EhcacheBackedProxyGrantingTicketStorageImpl class is not getting the class. Do I need to setup a different ehcache cache manager in a different file? Is there something else we need to do?
