  Solution:
  
  Check SAML Configuration: Review the SAML configuration in both the IdP and SP. Ensure that all required attributes and elements are correctly defined and mapped.

  Debugging: Enable logging for SAML transactions to capture detailed information about the SSO process. This can help identify where the configuration is failing.
