ldifde - what is wrong with my input in order to expand schema in ad lds

I am trying to import an ldf file to my AD LDS instance so that I can set it up as a proxy.

C:\Users\administrator.SEC1>ldifde -i -f c:\windows\adam\MS-adamschemaw2k8.ldf s localhost -j c:\windows\adam

I am getting the following error.  What is wrong with my cmd above?

Connecting to "localhost"
Logging in as current user using SSPI
Importing directory from file "c:\windows\adam\MS-adamschemaw2k8.ldf"
Loading entries.
Add error on entry starting on line 16: Referral
The server side error is: 0x202b A referral was returned from the server.
The extended server error is:
0000202B: RefErr: DSID-031007EF, data 0, 1 access points
        ref 1: 'x'

0 entries modified successfully.

Thanks.
