In the "Juniper SRX Routers and Firewalls Feature Guide,
https://learning.motorolasolutions.com/search?t=Juniper+SRX+Routers+and+Firewalls+Feature+Guide
Setting the device RADIUS Shared Secret, the guide states to use the following:

set system radius-server <RADIUSserverIPaddress> secret <password>

After performing the above entry the router or firewall still requests a local login when connecting via SSH.
Command was entered with the incorrect RADIUS Server address

If the above command from the guide has been entered already and the Juniper device still requests a local login perform the following:

configure                                                   (enter configuration mode)
show system radius-server                          (show currently added radius servers)
delete system radius-server <server IP>    (repeat for each incorrect radius server)
commit

show system radius-server                        (verify the RADIUS servers are correct)
commit and-quit

Example of a correct output:

Perform another PuTTY SSH connection the Juniper device and verify domain credentials now work to login.
