Icon Sametime doesn't appears in client Lotus Notes

We are encountering a problem when the interconnection of Sametime with the Advanced 8.0 Domino 8.01. Authentication is done in the LDAP server (Novell NetWare 6.0), with access only Read Only. The Sametime is usually logged in LDAP and client Lotus Notes status bar appears that he is active. It turns out that the icons that show that the user is active in the environment and also in Lotus Notes and Notes AddressBook - the green icon aren’t displayed. Do you could help me?
