This commit fixes my last one in which the client would attempt to check the server signature (and fail) even if the key was not specified in the PAM config file.

Now the client will only try to validate the server signature if both the 'id' and 'key' parameters are set.
In other words, it still works OK if just 'id' is set (but without validation)
