The intra-mart Accel Platform allows SAML authentication even if the IdP metadata contains multiple certificates.
If the IdP metadata contains multiple certificates, a brute force check is performed and authentication will be processed when either certificate is considered valid.
However, if the old certificate is expired and a check is performed using that certificate, an error log will be output.
In that case, please delete the expired certificate on the IdP and update the IdP metadata again on intra-mart Accel Platform.
