[Bug 1065429] Re: Long passwords for authenticated repositories not handled well

[Brian Murray]

** Description changed:

  If there is a repository that needs authentication with a long password
- (>64 chars) this is not handled well in apt. It will simply cut it off
- and the authentication will fail with a error from the server instead of
- indicating that the password is too long.
+ or username (>64 chars) this is not handled well in apt. It will simply
+ cut it off and the authentication will fail with a error from the server
+ instead of indicating that the password is too long.
  
  The maximum size of the user/password needs to be increased and a proper
  error message on overflow needs to be given.
  
  To test this we need a repository with a long username/password.
