If you embedded Sisense in an iframe and implemented SSO, in some cases when using Explore or Safari browsers you might see the following error: "An error occurred while trying to authenticate you using Single-Sign-On. Please ask your administrator for assistance.". 

The reason this is happening is that Explorer & Safari are blocking third party cookies by default, so the JWT is invalid. This can be solved by changing the default configuration of the browser. 

1. In Explorer this can be done by following these steps:
   Open internet options -> choose privacy -> advanced. Then change Third-party cookies to "Accept": 
2. For Safari, you can find the instructions here: http://clubrunner.helpserve.com/Knowledgebase/Article/View/710/0/enable-third-party-cookies-for-safari.
