## Symptoms

- * After an AD password change, the user is unable to pass Preboot authentication with their new AD password. The old AD password (in Preboot) works correctly.
* After an AD password change, the user is prompted with the following popup message:   

  `"The Preboot password was changed successfully"`.   

  The new password works in Preboot for some time, after which the user receives the following popup message:   

  `"The password is in the history database and cannot be reused yet"`.   

  The new password then stops working, and the user must use their old password to authenticate to Preboot.   
* The FDE log file(dlog1) shows:  
  `
  lsass.exe:1340 [pwd sync] Your FDE password could not be synchronized`  
  `
  lsass.exe:1340 [pwd sync] The password contains the following errors:`  
  `
  lsass.exe:1340 [pwd sync] * The password is in the history database and cannot be reused yet.`  
  `
  FDE_srv.exe:2fd4 DAFCommunication Server Result Error. Command: SET_FDE_USER_INFO, Code: 500, Detail: An error occured while getting user info. `  
  `
  All user(s) either contained no auth data, were not assigned to the endpoint or could not be downloaded to the endpoint.
  `
* The Client UI log file shows:

  ```
  
  Tray_UI_462329907.ServicesManager.Call: "ShowBaloonInternal", "Password update failed:
  The password is in the history database and cannot be reused yet"
  ```

## Cause

When user authentication data is missing in the Full Disk Encryption database, user info is not sent to the server.
