What permissions of active directory (DOMAIN) should have the user of installation of SAP BPC MS 7.5?

I have an installation of SAP BPC MS 7.5, the user I used for installation have permissions to the USER domain, in the local server is added permissions administrator LOCAL.

In the server, BPC works fine, but when I try to access from a computer client not let me access tells me that the user is not authorized.

In other installations I've done, the user I use for installation have permissions to DOMAIN administrator, but on this occasion the client did not want to give that permission. I want to specifically tell the client, that permissions the user must have exactly, for BPC can run fine.

I welcome your comments and thanks in advance.
