Consider the following scenario:
- You install the Password Synchronization component of Identity Management for UNIX (IDMU) on a domain controller that is running Windows Server 2008 R2.
- A password for a user is synchronized between the domain controller and a computer that is running UNIX or Linux.
In this scenario, the Local Security Authority (Lsass.exe) process exits unexpectedly on the domain controller, and then the domain controller restarts. Additionally, the following event is logged on the domain controller:
Alert: USER32 Event
Source: <full computer name>
Last modified by: System
Last modified time: <time>
Alert description: The process wininit.exe has initiated the restart of computer on behalf of user for the following reason: No title for this reason could be found
Reason Code: 0x50006
Shutdown Type: restart
Comment: The system process 'C:\Windows\system32\lsass.exe' terminated unexpectedly with status code 255. The system will now shut down and restart.
The "full computer name" placeholder represents the fully qualified domain name (FQDN) of the domain controller.
This problem occurs because of a code defect in the Password Synchronization component. This code defect affects the memory size calculation for the heap allocation.
