Prevent the BlackBerry Enterprise Server fromretrieving contact information for specific users
If you are required by your organization to prevent BlackBerry device users from finding contact information for specific
users, you can specify a list of users that you want to prevent BlackBerry device users from finding contact information for
or you can filter users using an attribute in Microsoft Active Directory.
Before you begin:
• Configure the BlackBerry Enterprise Server to resolve email addresses and organizer data information using LDAP.
• If you want to filter users using an attribute, choose an attribute in Microsoft Active Directory such as Mail or any of the
extensionAttributes (extensionAttribute1 through extensionAttribute15). You can use the Active Directory Users and
Computers console to change the value for the attribute to HideFromBlackBerry for all users that you do not want
BlackBerry device users to find.
1. On the computer that hosts the BlackBerry Enterprise Server, click Start > Run.
2. Type regedit. Click OK.
3. Perform one of the following actions:
• If you are running a 32-bit version of Windows, navigate to HKEY_LOCAL_MACHINE\Software\Research In Motion
\BlackBerry Enterprise Server\Agents.
• If you are running a 64-bit version of Windows, navigate to HKEY_LOCAL_MACHINE\Software\WOW6432Node
\Research In Motion\BlackBerry Enterprise Server\Agents.
4. Create a String value named LDAPALPObjectCategory.
5. Change the value to one of the following options:
• If your organization uses Microsoft Exchange 2007 or Microsoft Exchange 2010, use
msExchDynamicDistributionList,Group,Person))(!(

<attribute>

=HideFromBlackBerry, where <attribute> is the
name of the attribute that you want to filter (for example, extensionAttribute1).
• If your organization uses earlier versions of Microsoft Exchange, use Group,Person))(!
(

<attribute>

=HideFromBlackBerry, where <attribute> is the name of the attribute that you want to filter (for
example, extensionAttribute1).
