Hi list,

I am recieving a WARN when two DataConnectors export the same attribute.
(Think of eduPersonAffiliation, with "member" from a static DC, and the
rest from an LDAP DC.)

2020-12-29 15:24:26,934 - WARN
[net.shibboleth.idp.attribute.resolver.impl.AttributeResolverImpl:548] -
Attribute Resolver 'ShibbolethAttributeResolver': could not export
attibute 'eduPersonAffiliation' from data connector 'staticAttributes'
since an attribute of that name already exists.

There's no explicit AttributeDefinition for eduPersonAffiliation in the

Is this intended behaviour? The Wiki currently tells otherwise, defining
a clash as: Data Connector exports an attribute with the same name as an
Attribute Definition.
