 ===== Duplicate attributes in Shibboleth IdP 4.x ===== ===== Duplicate attributes in Shibboleth IdP 4.x =====
 If you notice that your IdP 4.x transmits duplicate attributes, you probably have copied the file ''conf/attribute-resolver.xml'' from an IdP 3.x without adapting it. The IdP has duplicate transcoding rules: once in ''conf/attribute-resolver.xml'' and once in the Attribute Registry. Remove the Attribute Encoder lines from the resolver configuration so that it looks like in [[de:shibidp:config-attributes-minimal|this example]]. If you notice that your IdP 4.x transmits duplicate attributes, you probably have copied the file ''conf/attribute-resolver.xml'' from an IdP 3.x without adapting it.

 +===== Duplicate Transcoding Rule =====
 +If you get the error message below, you probably have a duplicate attribute in your Attribute Registry. Maybe you imported attributes from a file like our dfnMisc.xml ([[de:shibidp:config-attributes#edupersontargetedid_und_andere_verbreitete_attribute_hinterlegen|German documentation]]) **and** you have defined one of the attributes in an individual .properties file underneath ''conf/attributes/custom/''? Make sure that each attribute exists in the Attribute Registry exactly once.

 +===== IdP/SP is no longer part of the eduGAIN metadata =====
 +
 +Our downstream eduGAIN metadata (the eduGAIN metadata we distribute to DFN-AAI) have never contained entities from DFN-AAI. We filter them out because your systems already know them from DFN-AAI metadata and we do not want to distribute duplicates. To check whether an entity is part of the eduGAIN metadata, please search for it in the [[https://technical.edugain.org/entities|eduGAIN Entities Database]].

 +===== SP Metadata: AuthnRequestsSigned and WantAssertionsSigned =====
 +
 +A Service Provider can announce in its metadata that it
 +  * signs Authentication Requests it sends to IdPs, and/or
 +  * wants to get signed SAML assertions back.
 +
 +Our metadata administration tool only displays this information if it is included in the xml files upon initial upload to the metadata administration. Please extend your SP metadata like this:<code xml><md:SPSSODescriptor AuthnRequestsSigned="true" WantAssertionsSigned="true" protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol"></code>
