Hi,
Sorry for the late reply, I've only just had some time allocated to look into this.
It looks like if I add anything to /opt/idp/conf/attribute-resolver.xml or attribute-resolver.xml in the same directory, it is lost after Gluu restarts. These are the two files I need to edit according to the shibboleth page linked. I am assuming this is because this file is rebuilt on a server start?
Could you clarify how I should add in these configuration changes so they are persistent through reboots/restarts of services?
Thanks
