Access issue with some publisher platforms

[Francis Jayakanth]

HI, we are using Shibboleth IdP 4.0.1 along with Azure AD tenant to facilitate federated access to subscribed online resources from the various publishers like Elsevier, ACS, Wiley etc. While the access is working fine on most of the publishers' platforms, we are having issues with a few platforms that include Springer Link, Springer Nature (for Nature branded journals), and Web of Science.

The attributes released from the IdP are: eduPersonEntitlement, eduPersonScopedAffiliation, and eduPersonTargetedID.

The Springer site, link.springer.com throws up an Application error with Issue reference number:
1a4582-SAMLmessagevalidationfailedduringSingleSign-On

Can anyone help us to resolve the issue?

Thanks in advance, Francis
