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

messages from telnet attempts as "test1" in authlog:

NAME

       wtmps, btmps - user login information

SYNOPSIS

DESCRIPTION

       and hold user and accounting information for such commands as and (see last(1), who(1), write(1), and login(1)).

       File  contains  bad  login entries for each invalid logon attempt.  File contains a record for all logins and logouts apart from accounting
       records.  These files contain structure, the key elements of the structure are given below:

		      char ut_user[]		User login name
		      char ut_id[]		Unique Id to distinguish an entry
		      char ut_line[]		Device name
		      pid_t ut_pid		Process Id
		      short ut_type		Type of Entry
		      struct ut_exit		The exit status of a process
		      struct timeval ut_tv	Time entry was made
		      char ut_host[]		Host name, if remote
		      uint8_t ut_addr[] 	Internet Address of the Host,
						if remote
		      short ut_addr_type	Flag to identify type of address
						in ut_addr

	      #define WTMPS_FILE      "/var/adm/wtmps"
	      #define BTMPS_FILE      "/var/adm/btmps"

       Note that and tend to grow without bound, and should be checked regularly.  Information that is no longer useful should be removed periodi-
       cally  to prevent the file from becoming too large.  Also note that and are not created by the programs that maintain them.  Thus, if these
       files are removed, login record-keeping is turned off.
