Restricting Secure Impersonation / Proxy Users

[#1]

For Secure Impersonation / proxyusers, is there a way to blacklist certain users so even if they are added to the group, they won’t be allowed to be impersonated?

[#2 · Accepted solution]

No, one can only whitelist the hosts and groups that can be impersonated by the proxy user. You may want to define a new group in this case.
