Cause :

This event is logged when wide character to multibyte character conversion error.

Resolution :

Fix possible failures for Win32 API

Password propagation failed because Password Synchronization experienced a failure attempting to call a Windows API.

Read the full text of the error message in Event Viewer to obtain the exact Windows error code.

To correct the error, try the following steps in order, moving on to the next step only if the current action failed to clear the error condition:
  1. Free virtual memory by closing unused applications.
  2. Restart the Password Synchronization service.
  3. Restart the computer on which the error was generated.
Verify :

Retry Windows to UNIX password synchronization for any failed user password change attempts to verify that Password Synchronization is operating normally. Password Synchronization is operating normally when password synchronization succeeds and is operating under warning conditions if synchronization fails for some passwords but succeeds for others.

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