  The shared secret is correct.

  This is an issue with PAM on the client machine.  Some other module is
doing password checking.  When the password check fails, it re-sets the
password to "INCORRECT".  That password is then sent to the pam_radius
module.

  Go fix the client so that the PAM modules don't change the password.
