Shibboleth Developers

[Markus Ludwig Grandpre <>]

Another trial:

public Map<String, BaseAttribute> resolve(
    ShibbolethResolutionContext resolutionContext)
    throws AttributeResolutionException
  {
    ...

    Set <Entry<String, ResolutionPlugIn>> s = r.entrySet();

    for (Entry<String, ResolutionPlugIn> e : s)
    {
        log.debug("Key: " + e.getKey());
        log.debug("Value: " + e.getValue());
    }
    ...
  }

with same results:

DEBUG MyShibbolethDataConnector.java(85): Key: eduPersonPrincipalName
DEBUG MyShibbolethDataConnector.java(86): Value: 
edu.internet2.middleware.shibboleth.common.attribute.resolver.provider.attrib
uteDefinition.ContextualAttributeDefinition@31db04
DEBUG MyShibbolethDataConnector.java(85): Key: myShibboleth
DEBUG MyShibbolethDataConnector.java(86): Value: 
edu.internet2.middleware.shibboleth.common.attribute.resolver.provider.dataCo
nnector.ContextualDataConnector@1220fd1

One DataConnector object and only ONE AttributeDefiniton object (instead 
of expected THREE objects according to attribute-filter.xml).

Any help is highly appreciated,
Markus
