DescriptionThis article describes that authentication prompt is not showing when policy is having user configured.
SolutionPolicy is configured with the user however authentication prompt is not received to the user
This can happen due to two reasons:
1) Traffic is not matching the configured policy
2) There is policy configured to allow the traffic without any authentication
If there is policy without any authentication, then firewall will first select the policy which does not have any authentication configured to allow the traffic though the policy with authentication is on top.
In the above picture policy 12 is configured with the user however traffic will always flow from the policy 11 as there is no user is configured in it.
