Take this exam to become certified in Zscaler Private Access (ZPA) as an Administrator. I had someone ask for a run through of what happens if you set Active Directory up incorrectly. Hi Jon, The CORS error is being generated by the browser due to the way traffic is handled by ZCC. Kerberos Authentication for all authentication domains is in place Follow through the Add IdP Configuration wizard to add an IdP. if you have solved the issue please share your findings and steps to solve it. What then happens - User performs the same SRV lookup. IP Boundary can be simpler to implement, especially in environments where AD replication may be problematic, or IP Overlaps / Address Translation may hamper AD Site implementation. But there does not appear to be a way in the ZPA console to limit SRV requests to a specific connector. Prerequisites Obtain a SAML metadata URL in the following format: https://.b2clogin.com/.onmicrosoft.com//Samlp/metadata. Analyzing Internet Access Traffic Patterns will teach you about the different internet access traffic patterns. Kerberos Authentication DFS Uses Active Directory extensively for Site selection and Inter-Site path cost.
