We have a large problem..
In our NetWeaver 7.0 system, a user has sap_j2ee_adm rights. However, he wasn't supposed to have rights to access user administration on the portal. Someone has changed the rights of the role sap_j2ee_admin to establish this, but doing so, nobody is allowed to access the UME anymore. We cannot change anything! The users are validated against the ABAP stack, which we can access normally.
Does someone know how to reset these rights?
