Cannot mount AFP sharepoint directly

I have a sharepoint set up in Lion Server. When I try to connect from a client computer via Go to Server I get the error "the share does not exist. Please check the share name". If I type the addres AFP://servername.domain.com, It takes me to the root of the shares and I can pick the share I want. If I type AFP://servername.domain.com/share, it fails with the above error.
