Registry Value LastLoggedOnUser is no longer correctly evaluated after installation of SafeGuard 5.x

  • Article ID: 117325
  • Updated: 03 Jan 2014


After SafeGuard has been installed and the SafeGuard Credential Provider is being used to logon to the system, the registry value for LastLoggedOnUser is not populated correctly anymore. Resulting in a state that LastLoggedOnSAMUser and LastLoggedOnUser are no longer filled with the same value.

Could cause logon problems in environments where customers that are using 3rd party software (i.e. Computrace or Frontrage Discovery), which pulls the "username" value from the "LastLoggedOnUser" registry key - which is no longer populated correctly after SafeGuard Client is installed and SafeGuard Credential Provider is being used.

What To Do

This issue has been fixed with the release of SafeGuard 6. If updating to SafeGuard 6 is not possible, a hotfix for SafeGuard 5.60.0 is available upon request from Sophos support.

If you need more information or guidance, then please contact technical support.
