URL validation was added to the SAML integration which affected some customers that were using legacy URL configuration. If you cannot log in using SAML, please enter a LiveChat for assistance, or you can adjust your Assertation URL. Legacy URLs may contain a double forward slash after threatlocker.com - examples below. https://betaportalapi.X.threatlocker.com//portalApi/AuthenticationSAML/AssertionConsumerService To fix, this needs to be changed to a single forward slash: https://betaportalapi.X.threatlocker.com/portalApi/AuthenticationSAML/AssertionConsumerService **Please note that X is your Instance and should not be changed from the current value (B, C, D, F, G, H etc)
