    Browser specific issue.


    - We can't control browser related issues. That's why we introduced "Included IP Range(s)" field in RSSO settings for Kerberos in RSSO 19.02 & later versions.
    - You can specify a range of IP addresses. Only the clients whose IP address match with the IP addresses configured will be authenticated by Kerberos authentication.
    - All other requests coming from the IP addresses that are not configured in this field are passed on to the next IdP in the authentication chain.
    - Here is the document for the same :
    - If you are on older version of RSSO then you will have to upgrade to 19.02 or latest version to use this feature.
