Security constraint when Non Admin users trying use login.doDescriptionWhen non-admin user trying to login using login.do eg : <instance_name>.service-now.com/login.do. Users are observing "Security constraint prevent access to requested page"CauseIt does not mean the user is unable to login, the user has logged in. However, due to ACL on login_redirect user is experiencing "Security constraint prevent access to requested page" "ACL on login_redirect might be preventing access to the page" ResolutionACL : "login_redirect" - https://<instance_name>.service-now.com/nav_to.do?uri=sys_security_acl.do?sys_id=cbfb0ca3931102009c8579b4f47ffbc2 Above mentioned ACL is responsible for the security constraint issue, it need snc_internal and snc_external role for the login redirection. Non-Admin user trying to login has role "snc_internal", after adding "snc_external" role, user is able to see the page.
