Directory Data Services (DDS) lookup is causing an error of 'Address <email address> is not unique. The following entries share the same email address:'

Either a DDS error, alert notificaiton, or both can occur.

• DDS error: com.symantec.sms.dds.api.exception.AddressNotUniqueException: Address
• Alert notification is as follows:

======================= ALERT NOTIFICATION ================================              

The Directory Data Service status is as follows:


Host : Local Host

Date : Monday, Apr 05, 2010 02:34:56 PM EEST Status : A directory data integrity error has occurred. An email address is associated with more than one directory entry.

Please check the directory data service logs for more information. 

LDAP/Active Directory sources are being used for redundancy and/or contain common information such as name or email address.

By design, Messaging Gateway requires unique data for DDS functions other than Recipient Validation.

If there are multiple DDS sources that contain common information:

• Select Recipient Validation for the redundant sources

If there is only one DDS source, there are entries in the LDAP/Active Directory that are not unique:

• Change or modify entries so that there is a unique lookup for each entry

From the Administrator Guide, Adding a data source:

"For authentication, address resolution, or routing data sources, the results that are returned must be unique. Therefore you cannot have identical or overlapping (where two data sources can potentially return the same result) data sources. If the Directory data integrity errors alert is configured on the Alerts page, that alert is triggered when this condition is detected."
