When a customer upgrades WS from 10.4.4 or 10.4.5, a new column, 'userauthenticationtype', is created in the 'users' table in the database. The default value is set to '(null)'. This prevents administrators from changing passwords and/or logging in to WS after upgrade.


You can fix this issue by deploying the update to WorldServer 10.4.5, available on FTP.

If you cannot deploy it, contact the SDL Support Team:

  •     Log on to your "My SDL" Account.
  •     Log a support request via Support & Education Support


  • All systems running WorldServer 10.4.5 should have this hotfix applied.
  • The fix for this issue is also available in WS 11.1.1.
