Problem: Single Sign-On stops working after upgrading Tableau Server
Solution:
- Tableau recently updated their signature algorithm requirements. SHA-1 is no longer supported. The latest version of the WordPress SAML IDP plugin uses SHA-256 algorithm to address the issue.
- The certificate must use a secure signature algorithm, for example SHA-256. If you attempt to configure Tableau Server for SAML with a certificate that uses SHA-1 signature hash, Tableau Server will reject the certificate.
