3594546 - SAP Signavio SSO with Keycloack is not working

We are using Keycloack as a SAML-system and always getting an error during the SSO-login. 

Please check within the Keycloack attribute mapper, if there is an automatic attribute "role list". If yes, please remove this attribute as this attribute is sending the user roles instead of one attribute with different values, as different attributes with one value and all attributes have the same name.
