Anyone got WebAccess 2018 working successfully behind Access Manager
(4.4)? It worked well with GroupWise 2014 using an identity injection,
but this no longer seems to work with GroupWise 2018.

I saw the same thing with the GW Admin Console, but I was able to do a
form fill to get that working again. So far I haven't had any luck with
a form fill for web mail, and it is certainly more complicated than the
identity injection method.
