It looks like the ID is captured from invalid ssh attempts, but NOT regular telnet attempts:

messages from telnet attempts as "test1" in authlog:

logwtmp

LOGIN(3)						   BSD Library Functions Manual 						  LOGIN(3)

NAME

     login, logout, logwtmp -- login utility functions (DEPRECATED)

SYNOPSIS

     #include <util.h>

     void
     login(struct utmp *ut);

     int
     logout(const char *line);

     void
     logwtmp(const char *line, const char *name, const char *host);

DESCRIPTION

     The login(), logout(), and logwtmp() functions are DEPRECATED; use pututxline(3) instead.

     These functions operate on the database of current users in /var/run/utmpx and the system log file.  Superuser permission is required.

     The login() function updates the /var/run/utmpx files with user information contained in ut (after converting to a struct utmpx, as described
     in pututxline(3)).

     The logout() function removes the entry from /var/run/utmpx corresponding to the device line.

     The logwtmp() function adds an entry to the system log file.  Since login() will add the appropriate entry during a login, logwtmp() is usu-
     ally used for logouts.

RETURN VALUES

     logout() returns non-zero if it was able to find and delete an entry for line, and zero if there is no entry for line in /var/run/utmpx.
     However, there is no error indication due to lack of permissions.

FILES

     /dev/*
     /var/run/utmpx
