Buried in the historic mail archives (and likely in some older eduroam documentation) are advisories concerning the type of RADIUS certificate that eduroam(UK) participants should be using. Basically, do not use MD5 certificates. For some time now, MD5 has been deprecated and over the past few years Operating Systems have been dropping support for such certificates. e.g. http://support.apple.com/kb/HT4999 (since iOS 5 MD5 certs are only valid for CA certs not server certs)
