SYMPTOMS
When you run the Microsoft Exchange LDAP management agent (MA), which uses Cdir_ldp.exe, many objects may be deleted unexpectedly if you are using Delta or Full mode. Additionally, the following error may be logged in the Zscript.log file:
CAUSE
This error occurs if network connectivity is lost during the discovery process. Before you install the hotfix that is described in this article, the "Unable to read LDAP message" error is not marked as an error message. Therefore, the %error% test condition that is located in the Mascript.scr file is not met after the "Execute Cdir_ldp.exe" statement and before the "Execute Importt.exe" statement. This allows the synchronization engine (Importt.exe) to run even though Cdir_ldp.exe has not successfully completed the discovery process against Microsoft Exchange Server.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
Full mode and Delta mode for Cdir_ldp.exe differ only in the manner in which Cdir_ldp.exe writes the import file. In Full mode (before you apply this hotfix), all deleted objects are excluded from the Import file. Therefore, if the synchronization engine (Importt.exe) runs in Full mode and communication is lost, the import file is incomplete and all of the missing objects are deleted from the metaverse.
In Delta mode, Cdir_ldp.exe compares objects in Exchange and in the Connector space to determine if objects should be deleted. This causes the CD object to be looked up in the Connector space. If the object is missing, a deletion transaction is written to the import file. This is an example of a deletion record in the import file:
-LDAPOBJECTDEL: DEL
-dn:
n=ChesterC,cn=Recipients,ou=MMS,o=Microsoft,ma=ExchangeMA,DsaName=MMSServer,ou=Applications,dc=microsoft,dc=com
