+'@backstage/plugin-auth-backend': patch
+---
+
+Add support for the majority of the Core configurations for Passport-SAML.
+
+These configuration keys are supported:
+
+- entryPoint
+- issuer
+- cert
+- privateKey
+- decryptionPvk
+- signatureAlgorithm
+- digestAlgorithm
+
+As part of this change, there is also a fix to the redirection behaviour when doing load balancing and HTTPS termination - the application's baseUrl is used to generate the callback URL. For properly configured Backstage installations, no changes are necessary, and the baseUrl is respected.
