Como removo os erros fed ?

    

Answer 1

No ADFS, esses erros são provenientes dos pontos de extremidade do ADFS.

2016-11-07 12:49:08 ERROR XMLTooling.ParserPool : error on line 1, column 3893, message: no declaration found for element 'fed:ClaimTypesRequested'
2016-11-07 12:49:08 ERROR XMLTooling.ParserPool : error on line 1, column 24931, message: no declaration found for element 'fed:TargetScopes'
2016-11-07 12:49:08 ERROR XMLTooling.ParserPool : error on line 1, column 26031, message: no declaration found for element 'fed:ApplicationServiceEndpoint'
2016-11-07 12:49:08 ERROR XMLTooling.ParserPool : error on line 1, column 26285, message: no declaration found for element 'fed:PassiveRequestorEndpoint'

Então, eu só tive que desativar os pontos de extremidade não utilizados no Gerenciamento do ADFS > Serviço > Endpoints. Em seguida, ele removeu os erros posteriormente.

    

Answer 2

Não sei se você encontrou a solução, mas acabei de encontrar a mesma situação e tenho uma solução: No arquivo shibboleth2.xml, altere o parâmetro "validate" para "false", como isso:

<MetadataProvider type="XML" validate="false" file="/etc/shibboleth/FederationMetadata.xml"/>

No meu caso, posso ser redirecionado na página de login do Idp e enviar de volta ao meu aplicativo.
