Hi everyone! I'm new here and I have some doubts.<div><br></div><div>OP returns something that identifiers users uniquely.</div><div><br></div><div>Must (or should) OP return always the same identifier for an user?</div>
<div>if not, that is bad to RPs, isn't?<br clear="all"><br></div><div>I noticed that I have different ways to use my Google openid and each one may return something different (or RPs are doing something wrong).</div>
<div>
ex:</div><div><a href="https://www.google.com/accounts/o8/id">https://www.google.com/accounts/o8/id</a> (OP identifier)</div><div><a href="http://google.com/profiles/LOGIN">http://google.com/profiles/LOGIN</a></div><div>
<a href="http://www.google.com/profiles/1234567890">http://www.google.com/profiles/1234567890</a></div>
<div><a href="https://www.google.com/accounts/o8/id?id=blablablablabla">https://www.google.com/accounts/o8/id?id=blablablablabla</a></div><div><br></div><div>Thanks</div>
