I think it would be the best to add a method to the GeoServerSecurityManager to check if there is an anonymous authentication.
would be fine.

FWIW, I think the reason the AnonymousGeoNodeAuthenticationToken is extending UsernamePasswordAuthenticationToken is to hold the cookie value that ties the anonymous user to a Django session.
It seems like this could be done differently for sure, especially to play well with the proposed functionality or other security aspects that would (logically) expect an instanceof AnonymousAuthenticationToken check to work.
Thanks for pointing this out

Hi Christian,
your comment makes me think GeoNode should rethink the way they handle
user authentication.
Regardless, what about my question? How to best check if the user is the anonymous one?
Cheers

Strange
Looking at
https://github.com/GeoNode/geoserver-geonode-ext/blob/master/src/main/java/org/geonode/security/AnonymousGeoNodeAuthenticationToken.java
I am asking me two questions
- Credentials for an anonymous user ?
- An individual user name for an anonymous user ?
We solve the problem with
GeoServerUser.createAnonymous()
At a minimum I think they should use
org.springframework.security.authentication.AnonymousAuthenticationToken
and we can check with
SecurityContextHolder.getContext().getAuthentication()
Just my 2 cents

It seems to be they are implementing the standard authentication java interfaces
to have GeoServer use GeoNode as the user and authentication source:

However sometimes we do have the actual user logging in, in that case
I believe we should use that to drive the limits instead of a cookie.
However… how does one know if the user is the anonymous one?
Just checking if the authentication is a AnonymousAuthenticationToken
seems a bit weak, I’ve for example noticed that GeoNode has
its own AnonymousGeoNodeAuthenticationToken which is, for some
strange reason, a subclass of UsernamePasswordAuthenticationToken
Not sure how to understand. Does GeoNeode extend the Geoserver code ?. I do not know Geonode but how is the class
AnonymousGeoNodeAuthenticationToken injected into GeoServer ?
