Error while creating user - not authorized to assign profiles or roles

I have configured CUA according to the help.sap.com instructions. I am getting this error (in TCODE SCUL)..

+You are not authorized to assign profiles

Message no. 01589

You are not authorized to assign profiles to users or to cancel the authorization.+

I can create the user, change the address data, and initial password.

I get errors on assigning to a group, parameters, or the role and profiles.

We are on NW Mobile 7.1 (ABAP stack only) SP05.

I've read Note "492589 - CUA: Minimum authorizations for communications users."

It mentions SP07. Is this not compatible?
