How To Fix SAML2061 - La signature du message "&1" de l'émetteur "&2" n'est pas valide.

SAP Error Message - Details

• Message type: E = Error

• Message class: SAML2 - SAML2 Nachrichten

• Message number: 061

• Message text: La signature du message "&1" de l'émetteur "&2" n'est pas valide.

Quelle est la cause de ce problème?

The signature check in the SAML message &V1& was not successful. The
reason can be one of the following:
The public key ( certificate ) of entity &V2& is missing from the PSE
file.
The key ( certificate ) of the issuer &V2& is flawed.

Réponse du système

The signature check was unsucessful and the SAML message could not be
processed.

Comment corriger cette erreur?

Check the entries in the developer trace of the application server.
Check the entries for keys in the SAML2 PSE. In transaction STRUST,
compare the certificates of the corresponding PSE with those that your
SAML2 partner provided.

Procédure pour les administrateurs système

Check the existence of the partner certificates and their correctness.
Errors occur, for example, when the certificate has expired, or the when
the certificate requires a chain of certificates to check the signature.
