XADM: Information Store Unexpectedly Dismounts When Clients Connect (818580)

SYMPTOMS

The information store may dismount without generating an error message or error event. When you remount the store, it dismounts again after a short time. When you perform additional troubleshooting steps to determine the cause of this problem, you may experience one or more of the following behaviors:

When you mount a blank store, it does not automatically dismount until a client program logs on.
When the client program connects to the blank store, you receive a message that the client program is retrieving data from the Exchange server, and then the information store dismounts.

CAUSE

This problem occurs if the information store tries to create a token object for a domain distinguished name (also known as DN) where the domain controller (DC) portion is made up of lowercase letters (dc=). This problem may also occur if a user distinguished name contains lowercase domain controller separators (dc=).

The information store tokenm code uses a case-sensitive STRSTR function to locate the DC= portion of the distinguished name. If the distinguished name uses lowercase letters similar to the following example, the tokenm code cannot determine the domain controller:

cn=username,cn=users,dc=domain,dc=corp,dc=example,dc=com
