When using radtest, which is a test tool that comes with FreeRadius, I get an exception System.InvalidOperationException: Invalid Message-Authenticator in packet 224.

$ radtest user password localhost 1812 0 12345
Received packet from 127.0.0.1:56039, Concurrent handlers count: 1

Checked the secret? That is what you would get with an incorrect secret if a message-authenticator attribute is included

Thanks. It wasn't the secret but something else in the params I was passing that I didn't realize until I tool a closer look. The server and port needed to be connected with a :. Sorry about that.
