Problem using delegated identity

[Ahmad Gharbeia]

Greetings,

I'm having trouble using delegated OpenID identity with some, but not
all, of the websites which claim to support OpenID.

I'm unable to log in to demand.openid.net nor wiki.openid.net with my
delegated OpenID [ahmad.gharbeia.org], which I use to log in to many
other sites, including pibb.com and many others.

Needless to say, I can log-in, if I enter the delegated provider's URI
directly, so it seems to be a problem in my delegation code, or these
consumers are unable to handle delegates.

I thought it was a v2.0 vs v1.1 issue so I changed the delegate
announcement to another which is 1.1 only, but still I get:
"failed for the OpenID you entered" for the first, and "Authentication
error; not a valid OpenID." for the second.

I tried several identity providers as delegates.

I'm unable to use with some other services as well, like scrapplet.com
and idntiti.com, both of which seems to be using the same log-in applet

Any insights?

Regards,
Ahmad
