the unit name is no longer than 256 characters and does not contain a slash (/), that the unit contains
no more than 100 subunits, and that you preceded the unit name with a slash (such as /Sales).
• Make sure the storage system time and Active Directory server time do not differ by more than five
minutes. If they do, you must adjust the storage system time, time zone, or both to ensure that they
match (as described in “Changing the System Settings” on page 69).
• Even if the storage system and Active Directory server are in the same time zone and have the same
time, errors might still occur if the Active Directory server adjusts for daylight saving time. In this case,
you must change both the time zone and time on the storage system. For example, if the Active Direc-
tory server time is 2:00 P.M. in the Central Time zone (GMT-06:00), you would set the storage system
time zone to Eastern Time (GMT-05:00) and then set the time to match the Active Directory server
(14:00). If you do this, do not synchronize the storage system with an NTP server, as the time will be
readjusted based on the time zone.
• Make sure the administrator user name and password for accessing the Active Directory server are
valid and have sufficient privileges for adding the storage system to the Active Directory tree.
Not all of my Active Directory users or groups were added to the storage system.
The storage system can accommodate a maximum of 128 users and 128 groups. If the selected
organizational unit on the Active Directory server has more than that, the excess users or groups will not
be added to the storage system.
To better control which users or groups are added to the storage system, you might want to create a new
organizational unit that contains the appropriate number of entities, switch back to local authentication
mode (as described in “Changing the Authentication Mode” on page 53), and then switch to Active
Directory authentication mode again, specifying the new organizational unit.
The user names that appear on the storage system do not match the names that appear in
the Active Directory tree.
The storage system displays the User logon name that appears on the Account tab in the Properties
dialog box on the Active Directory server. This name might differ from the name that appears in the Active
Directory tree. To ensure that the names are the same, you can either change the User logon name to
match the name displayed in the tree, or change the name in the tree to match the User logon name.
The storage system stopped synchronizing with the Active Directory server.
When you click Users in the navigation bar, the Users & Computers page appears. This page indicates
the current authentication mode above the list of users. For Active Directory authentication mode it also
