8.In the Search DN field, set the distinguished name of the search base (i.e. the domain name where the search starts for the user name). Note: If the Enable Authorization checkbox is not checked, this field must include the entry where the KVM Admin Group is created. Consult the LDAP/S administrator about the appropriate entry for this.
9.In the Admin Group field, key in the group name for KVM administrator accounts. Note: If the Enable Authorization checkbox is not checked, this field is used to authorize accounts that are logging in. Accounts that are in this group have full access rights to the KVM. Accounts that are not in this group have user access rights to the KVM (See the User Management section of this manual for details on account permissions). Consult the LDAP/S administrator about the appropriate entry for this.
10.On the LDAP server, set the access rights for each user (The following sections describe how to configure LDAP/S for use with the KVM switch).
