How to display relevant error to user

[IRus]

IListUserManager.getUserByName - for example I know that passsword is wrong, or username not exists. Or password expired, etc. How can I show this message in users client?

Hello,

I guess you implemented a custom HTTPAuthentication. In the method getUser, you can alter the response with the parameter ctx. But no mechanism is designed yet to explicitly send a custom response for an unauthorized user.
