PHP OpenID 2.0.0RC1 and Sreg

[Marco Bonetti]

Hello,

I'm writing an OpenID server based on the 2.0RC1 PHP OpenID library. The 
authentication itself works pretty well, but I'm having a slight issue 
with relaying parties requesting sreg data:

[...]openid.sreg.required=email%2Cnickname[...]

My server replies:

[...] openid.mode=id_res [...] 
openid.ext0.email=my%40email.com&openid.ext0.nickname=mynickname [...] 
openid.ns.ext0=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1 [...]

Unfortunately, all the RPs I tested choked on this.

Could this be a bug in my code (or in the library) or rather an 
incompatibility issue, i.e. the RPs expecting an sreg/1.0 reply and 
being unable to handle the sreg/1.1 chunk they receive instead?

Do you see any way around this issue?

TIA,
cheers,
