Hi,  
I´m succesfully using RADIUS authentication for my cnMaestro 2.4.1-r10 on premises deployment. The problem is, after enabling it, I can´t login anymore with the local users. It is only accepting RADIUS users.

The issue is happening also on another 3.0.4 deployment I have.

How can I troubleshoot this or which information may I provide you?

Thanks

Hi dmayan,

It is expected behavior. As of now we cannot allow multiple Authentication in modes in parallel, only one of the selected modes will work (Primary/Secondary). Fall back to secondary authentication server (Local users) happens only in case of Radius server unavailability. We cant use both the Authentication simultaneously.
