Hi,
I imported issues from a csv file and a few users got accidently created.
I tried to delete them all, but one got stuck with this message:
The user someVeryLongName does not exist please select a user from the User Browser.
I tried to delete him from CWD_USER, but that seemed to be a bad idea, because he is still in the user management. 
Any suggestions?
Greetings
Marc
