Users not created up e-mail submission

Hi all -

Running RT 3.8.8 on Ubuntu 9.10 – recently upgraded from 3.8.7.

In 3.8.7 I had the AutogeneratedPassword working for new users who submitted
tickets via E-mail (link below)

but now in 3.8.8 it no longer works. In /var/log/messages I see the
following error when a new user submits a ticket via e-mail:

*Jun 18 08:54:17 help RT: RT::Authen::ExternalAuth::CanonicalizeUserInfo
returning Comments: Autocreated on ticket submission, Disabled: 0,
EmailAddress:, Name:, Password: ,
Privileged: 0, RealName: Jen McGrath
Jun 18 08:54:18 help RT: Couldn’t load user ‘’.giving up

I’m not sure what I’m missing or what got screwed up with the upgrade –
hopefully it’s something easy.

Anybody have any ideas?
