Configure optionally an extraction for auth 1.1 or auth 2.0 If this element is specified, the filter will attempt to parse out a payload for the identity v2.0 contract (either json or xml) and extract the username. Group will be as configured, or the default of PreAuth. The default quality applied to the header will be 0.6 If you want to have different groups for 1.1 and for 2.0 you need to specify them, else they will use the same default.
