[rt-users] RT could not load a valid user

[Torsten Brumm]

Hi RT Users,

Today i upgraded RT 3.4.4 to RT 3.4.5 and i get the following error on 
some Queues:

RT could not load a valid user, and RT's configuration does not allow 
for the creation of a new user for this email (USERNAME at COMPANY.com).

You might need to grant 'Everyone' the right 'CreateTicket' for the 
queue applications-mdm_pdm.

My Log says:

RT's configuration does not allow for the creation of a new user for 
this email (tob at brummix.de).  You might need to grant 'Everyone' the 
right 'CreateTicket' for the queue KNliv-Jabil.

I have granted globally CreateTicket to Everyone and this error only 
occurs on two different queues. I cross checked this queues and granted 
them also on queue base CreateTicket but still i get the error.

Any Idea???

Thanks
