And, the following message appeared twice before the import was interupted:
[crit]: Failed to create user : Must specify ‘Name’ attribute
(/opt/rt3/lib/RT/User_Overlay.pm:595)
[error]: Could not load create a user with the email address ‘’ to add

What could be the cause of the problem(s), and how can it (they) be solved?
