Live Universe Connect SAML metadata file, which is downloaded via https://<HOST>:<PORT>/sap/boc/ina/saml/metadata, sometimes may contain multiple X509 signing Certificates ( certificate for LUC, intermediate certificate, and root certificate).  When this LUC SALM metadata file is uploaded into LUC application in SAML Identity Provider, IDP only accepts the last signing certificate, which is not the signing certificate for LUC.

You notice the validity, expiry date and subject DN of signing certificate for LUC in SAML Identity Provider are not matched with the certificate for LUC.

Open the LUC SAML metadata file, and manually copy the X509 signing Certificate for LUC (which is usually the first certificate), and paste into the corresponding SAML Signing Certificate field of LUC application in SAML Identity Provider.

You can verify the validity, expiry date and subject DN of signing certificate for LUC in SAML Identity Provider are matched with the certificate for LUC.
