Hi,

I am trying to write a Memcached based implementation of an IDP
StorageService, to be able to run idp in 2 servers, without using Terracota.

I am running into trouble after the user authenticates successfully,
right after attribute filtering:

11:55:19.784 - DEBUG
[edu.internet2.middleware.shibboleth.common.attribute.filtering.provider.ShibbolethAttributeFilteringEngine:101]
- Removing attribute from return set, no more values: eduPersonPrincipalName

- Filtered attributes for principal 
.
  The following
attributes remain: [mail, transientID, name, logoutURL, contactMail,
primaryid]

edu.internet2.middleware.shibboleth.idp.authn.LoginContext.getAuthenticationMethod(LoginContext.java:176)
[shibboleth-identityprovider-2.1.5-slo7.jar:na]

If in the internal.xml i change from my Storage Service to the
EventingMapBasedStorageService, everything works ok. So the problem is
with my implementation of the StorageService. Maybe some object I am
persisting on memcache is not serializable.

Have anyone tried something similar? With success? Is there any other
way to have two idp using a StorageService that stores data in a central
repository?
