Reject username contains newline character

[Peter Balsianok]

Hi all,

I have tried to create unlang peace of code to reject username which
contains newline character at the end.

Here is my unlang code

if (&User-Name =~ /\n$/)  {
    update reply {
      &Reply-Message += 'Rejected: Realm ends with a CR'
    }
    reject
  }

But this code doesnt work.

Here is fragment of the debug messages:
