We're a new member of the UK federation, with three registered SPs, two operational, all using the same GlobalSign cert for attribute requests. The cert is valid through June of 2009; the Subject CN matches the KeyName for all three SPs in the federation metadata; and the CN is also the domain name for one of the two operational SPs. For both operational SPs, attribute requests fail with "unsupported certificate" errors, with at least three different IdPs. No successful attribute requests for any IdPs. (Both operational SPs work successfully with IdPs from other federations. The test SP also works successfully with the ProtectNetwork IdP when we include only the UK federation MetadataProvider in shibboleth.xml - however, no attribute request is made in the case of ProtectNetwork.) Relevant section from shibd.log for one of the failed attribute requests follows. Any idea as to what might be the problem, with our cert or otherwise?
