OAuth request "Token with symmetric siganture requested, but no symmetric signing key found"

[rmarinho]

I m getting this exception when using Oauth token endpoint::

"Token with symmetric siganture requested, but no symmetric signing key found"

this happens in STS.cs

try
{
var rstr = _sts.Issue(principal, rst);
token = rstr.RequestedSecurityToken.SecurityToken;
return true;
}

Am i m missing something?!

Ok found the issue, need to create the Symmetric Signing Key for the realm party..

I am getting plagued with this regardless of what I set up on the server or client. Any tips?

All I am trying to do is simply get the "OAuth2 Resource Owner Password Flow" sample working from IdentityModel.45 using v2.1 of the server.
