Gilles,

> 16:24:52.727 - DEBUG [edu.internet2.middleware.shibboleth.common.attribute.filtering.provider.ShibbolethAttributeFilteringEngine:114] - Filtered attributes for principal yoyo.  The following attributes remain: [uid, surname, givenName, commonName, transientId, email, telephoneNumber, mobileNumber]

So, it looks like uid is present and the IdP is releasing it.  The next thing to check is whether the SP is receiving it and dropping it because there is no mapping or there is some policy check being failed.  The SP logs will give you the information here; as far as the IdP is concerned, assuming you're using the default encoders, all is well.
