I am using Spring SAML extension to connect with ping federate IDP server. I exported the ping federate IDP metadata xml and put it our application (and referring same file in securityContext.xml file). Now when I am trying to start my application then spring saml throwing following exception:
Caused by: org.opensaml.saml2.metadata.provider.MetadataProviderException: Error filtering metadata from C:\Drive E\workspace\enigma_master\etc\saml\idp.xml

I imported the certificate (one that is under tag <ds:X509Certificate>) in my samlkeystore file but still the same issue. I googled the error and as suggested:
- I tried to remove
<ds:Signature>tag from idp xml file. - Disabling signature verification by setting property metadataTrustCheck to false in the ExtendedMetadataDelegate bean
above approaches working for me. But I don't want to modify/remove tag from IDP xml file, it should work as it is. Please let me know what wrong I am doing?
Also I want to know what is the use of <ds:Signature> tag in metadata xml and why its not working even after importing certificate in samlKeystore file. And what is the meaning of each child tags like <ds:SignedInfo>,<ds:CanonicalizationMethod>, <ds:SignatureMethod>, <ds:Reference>, <ds:Transform>, <ds:DigestMethod>, <ds:DigestValue>, <ds:SignatureValue>.
