ADFS - metadata


We have an issue with Rancher and ADFS authentication. Metadata generated by Rancher (https://XXXXXXXX/v1-saml/adfs/saml/metadata) is wrong: the location of SingleLogoutService is empty. So, it generates error on ADFS side when it reloads Metadata automatically.
Anyone has already solved this issue? Is it possible to set a location for the SingleLogoutService?
