This has happened to @BjornPehrson_47a0 and others from SWAMID, then some others from CESNET and now to people from GRNET. @MarcoFargetta_0c9b1 it seems like this issue was never resolved, but we need to take a look. I'm assured that these idps are working for other sps in edugain. Are we doing some wierd filtering in our config ?
