Event ID 8195 — UNIX to Windows Password Synchronization Service -- Run-time Issues

  • Article

Applies To: Windows Server 2008

UNIX to Windows Password Synchronization Service -- Run-time Issues indicates the functionality of UNIX to Windows password synchronization operations.

When Password Synchronization is configured for UNIX to Windows synchronization, and UNIX to Windows synchronization is functioning normally, passwords that are changed on UNIX hosts are synchronized on Windows-based computers and domains. The Password Synchronization pluggable authentication module (PAM) makes this possible by intercepting the password change request on the UNIX host, encrypting the password, and then sending the password change request to the Password Synchronization service running on the Windows-based computers with which it is configured to be synchronized.

Event Details

Product: Windows Identity Management for UNIX
ID: 8195
Source: Microsoft-Windows-IDMU-PSync
Version: 6.0
Symbolic Name: MSG_MEMORY_ERROR
Message: Internal error: Memory allocation failed. Check system memory resources.

Resolve

Correct memory allocation error

Memory allocation has failed in Password Synchronization. This can occur if the Windows Server operating system has insufficient virtual memory. Try closing some applications and programs that are not required and are using large amounts of virtual memory, and then restart Password Synchronization.  If this fails to correct the problem, try restarting the computer.

If the problem persists, verify that the computer is not configured to use the maximum amount of virtual memory:

  1. Right-click My Computer and then click Properties.
  2. On the Advanced tab, in the Performance area, click Settings.
  3. On the Advanced tab of the Performance Options dialog box, in the Virtual Memory area, view the amount of virtual memory allocated on the machine.
  4. Click Change to view the maximum allowable virtual memory.
  5. If necessary, change allocated virtual memory to the size recommended in the Total paging file size for all drives area of the Virtual Memory dialog box.
  6. If you have changed the allotted virtual memory amount, click Set, and then click OK.

Attempt to free virtual memory by closing unused applications, or closing all applications and restarting the server. If that fails to correct the error, contact Support Options from Microsoft Services (https://go.microsoft.com/fwlink/?LinkId=52267) for specific resolution information.

Verify

To verify the functional state of UNIX to Windows password synchronization, retry UNIX to Windows password synchronization. UNIX to Windows password synchronization is fully operational when the password synchronization succeeds, and functioning with warning conditions present if password synchronization fails for some passwords but succeeds for others.

If password synchronization succeeds for some passwords but fails for others, the UNIX to Windows Password Synchronization Service is likely fully operational, but there might be account- or computer-specific configuration problems preventing password changes from being synchronized on UNIX-based hosts.
