Hi all, I wanted to add a new user to Zope, so I copied it's login name from a document and pasted it into the user add form. That login name included strange characters which I couldn't see. Now I can't remove that user!!

If I understand the code in lib/python/AccessControl/User.py correctly there is no "valid id" check or the like for users.
Wouldn't this make sense? As the user name has to be sent via an http-header to login as this user, maybe one could limit the allowed names to strings which may be send as valid http header. (I.e. creating a user with a ':' seems to be pointless, if using basic http-auth. Hm, but people using a Cookie-based login may argue differntly.)
However so far I have not been able to create a user which I could not delete afterwards. It would be interesting to know what characters do trigger this issue ...
Cheers, Clemens
This is what happened: I use kmail as my mail client. I selected the login name from it and, somehow, as it was at the end of a line I moved the mouse and selected the next line too. I decided to copy and paste it all into the Zope add user form. Only the second line appeared, so I selected and deleted it all. Then the first line appeared into the login name field, I mean the user name, so I added that user without realizing that it included two special characters (hex) in its user name: A (new line) and D (carriage return). Of course, I couldn't log in as that user, so I decided to delete and readd that user. It wasn't possible to remove it. Zope answer was that it found a KeyError with the login name. You may reproduce it and remove that user with the solution Adrian van den Dries gave me.
