invalid Message-Authenticator! (Shared secret is incorrect.)

[Hegedus Gabor]

Hi I have a problem:

I get this message
*invalid Message-Authenticator! (Shared secret is incorrect.) *

But I checked the key and it equals.

What is the problem?

clients.conf:
 client 192.168.1.10 {
    secret = test  
    shortname=blablabla
}

thx
