You have to enable Auth Request Signature setting into encryption settings. Also, keep in mind that if you do not configure a keystore with a certificate you are using an auto generated certificate that it is valid for a year
Auth Request Signature - Enable signature of the Redirect Binding Auth Request, If you enable it the encryption and signing key would available in the SP metadata file and URL (JENKINS_URL/securityRealm/metadata). Encryption - If your provider requires encryption or signing, you can specify the keystore details here that should be used. If you do not specify a keystore, the plugin would create one with a key that is valid for a year, this key would be recreate when it expires, by default the key is not exposed in the SP metadata if you do not enable signing. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
