no entry in wtmp?

I was wondering why the session does not write an entry into wtmp. the command "who" does not display that butterfly-ed user. It can be found by "ps -ef|grep pts":

[harish@vostro ~]$ who
harish :0 2014-03-29 00:19 (:0)
harish pts/0 2014-04-02 17:19 (:0)
harish pts/1 2014-04-02 09:28 (:0)
[harish@vostro ~]$ ps -ef|grep pts
harish 14299 23456 0 17:19 pts/0 00:00:00 bash
harish 22584 25409 0 21:31 pts/1 00:00:02 mutt
harish 24814 14299 0 22:25 pts/0 00:00:00 /usr/bin/python /usr/bin/butterfly.server.py --unsecure
harish 25409 23456 0 09:28 pts/1 00:00:00 bash
harish 25742 24814 0 22:39 pts/3 00:00:00 /bin/bash -i
harish 25794 14299 0 22:40 pts/0 00:00:00 ps -ef
harish 25795 14299 0 22:40 pts/0 00:00:00 grep --color=auto pts

Due to the manner in which butterfly "logs in" users, you won't see an entry in wtmp or on who.

I haven't tested this, but maybe changing out 'su' with 'login' ?
