Hi Maurizio, I would use the " uid=admin,ou=Administrators,ou=TopologyManagement,o=NetscapeRoot" instead of "cn=Directory Manager". Here's the copy and pasted information from the Red Hat Directory Server Admin Guide. There are important differences between the Directory Administrator and the Directory Manager: * The administrator cannot create top level entries for a new suffix through an add operation. either adding an entry in the Directory Server Console or using ldapadd, a tool provided with OpenLDAP. Only the Directory Manager can add top-level entries by default. To allow other users to add top-level entries, create entries with the appropriate access control statements in an LDIF file, and perform an import or database initialization procedure using that LDIF file. * Password policies do apply to the administrator, but you can set a user-specific password policy for the administrator. * Size, time, and lookthrough limits apply to the administrator, but you can set different resource limits for this user.
