User is not displayed in Group Hierarchy option

Hello,

we have a NetWeaver 7.0 SP11 on Windows 2003 server 64Bits

MI user type is already implemented and synchronization is OK

The problem is in the NWA (mobile web administrator):

We create a Hierarchy Group without problems but, when we try to assign users to it, the list users does NOT show me any users.

We apply the Note:1005765 but do not work

Thanks
