Description

To make tokenfilter work with auth-header and noauth module. (needed e.g. for Kerberos authentication through an Apache/Nginx Reverse Proxy, that passes REMOTE_USER header), username must be set in the credentials object, because it is added to the Tokenfilter only if username is not null in the credentials object.

basically make ${GUAC_USERNAME} be replaced with the credentials passed though the REMOTE_USER variable.
