DescriptionError: User name or password is not valid.
Event InformationAccording to Microsoft :
Cause
This event is logged when User name or password is not valid.
Resolution
Check user name and password
Password propagation failed because of a user account name or password that is not valid or does not exist. Verify that the correct user account name and correct current password was entered, and try to change the password again.
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.
