SAML ADFS - Windows Integrated authentication

Description

We plan to authenticate in RocketChat via SAML, more precisely via ADFS using WIA (windows integrated authentication). So far we have all configured, but unfortunately a login window always appears when logging in via WIA (urn: federation: authentication: windows). Somebody here already had the problem, it doesn’t work with the current Rocket.Chat version.
