Hi Jorge,

Thank you for your answer. I have installed new version freeradius-3.0.20.
Added into policy.d/filter file (at the of the section filter_username)

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

Test request file test.req contains:
User-Name = "bob\n"
User-Password = "hello"

For sending Access-Request was used:
.../freeradius-3.0.20/bin/radclient -x -t 10 -r 1 -f test.req -d .
127.0.0.1:10812 auth testing123

The same result as in version 3.0.16 :(.
