I am trying to have oauth2-proxy forward the user's groups, using the X-FORWARDED-GROUPS header, to a GeoServer instance.
The problem is that if a user belongs to multiple groups, oauth2-proxy sends a header like this:
X-FORWARDED-GROUPS: group1,group2
GeoServer on the other hand expects groups to be separated by a semicolon. I haven't found a way to change either the GeoServer separator (related question), or what oauth2-proxy uses.
Is there a way to change the separator?
