Filter rules for Lotus Notes and Exchange Server Directory Synchronization

You can use filter rules to prevent specified directory entries from being propagated between Microsoft Exchange Server and Lotus Notes during directory synchronization.

For example, if the Notes Public Name and Address Book contain users from multiple Lotus Notes domains, by default, all the users from all the domains are propagated from the Address Book to Active Directory during directory synchronization. You can set up a filter rule to prevent certain users from being propagated, based on the domain in which those users are located.

To implement filtering, you have to add registry entries.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Note There is a limit of 10 filter operands.

To add a filter rule registry entry, follow these steps:

1.	Click Start, point to Run, type Regedt32.exe in the Open box, and then click OK.
2.	Locate and then click the following key in the registry: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LME-NOTES\Parameters
3.	On the Edit menu, click Add Value, type DXANOTES_filter_filtername in the Value Name box, click REG_SZ in the Data Type box, and then click OK. Note You can choose the text for the filtername value.
4.	In the String Editor box , type the Domino directory attribute, operand and filtertext, and then click OK. The directory attribute, operand, and filtertext should be separated by commas (,). The following is a list of valid operands: � EQ - Propagate if the specified attribute is equal to the specified filter. � NE - Propagate if the specified attribute does not start with the specified filter. For example, if the registry subkey has a value of CompanyName,EQ,Contoso, the filter will only propagate Domino users who have a CompanyName of Contoso to Active Directory.
5.	Quit Registry Editor.
