Symptoms

Audit events (event ID 565) for directory service access may contain truncated distinguished names for the Object Name entries. This problem may occur if the object server is "Security Account Manager."

This is an example of an audit with a truncated object name:
Event Type: Success Audit
Event Source: Security
Event Category: Directory Service Access
Event ID: 565
Date: 25/02/2002
Time: 13:19:39
User: NT AUTHORITY\SYSTEM
Computer: SAMPLEDCNAME
Description:
Object Open:
Object Server: Security Account Manager
Object Type: SAM_SERVER
Object Name: CN=Server,CN=Syst
New Handle ID: 11698960
Operation ID: {0,174552766}
Process ID: 324
Primary User Name: SAMPLEDCNAME$
Primary Domain: SAMPLEDOM
Primary Logon ID: (0x0,0x3E7)
Client User Name: SAMPLEDCNAME$
Client Domain: SAMPLEDOM
Client Logon ID: (0x0,0x3E7)
...
In this example, the object name is truncated to "CN=Server,CN=Syst. It should be "CN=Server,CN=System,DC=domainname,DC=com."

Cause

The object name length is set to the number of characters, instead of to the number of bytes. The distinguished name is stored as Unicode, which causes only half of the string to be processed.
