Deep link to candidate profile ?

Content

I am using this deep link:

Open a candidate file

http://client.taleo.net/enterprise/publicurl/viewProfile?candidateNumber= 5159

But when I swap the client name and use the variable of "candidate identifier" it does not take me to the candidate page, only to our landing page that we see after logging in.   Should I be using a different variable other than the candidate identifier?
