 Hmm... rlogin shows reference to rlogind... the man page contains

    Once the source port and address have been checked, rlogind proceeds with
    the authentication process described in rshd(8).  It then allocates a  

 so we check out rshd(8)...

 8. Rshd then validates the user using ruserok(3),  which uses the file
    /etc/hosts.equiv and the .rhosts file found in the user's home di-
    rectory.  The -l option prevents ruserok(3) from doing any valida-
    tion based on the user's ``.rhosts'' file, unless the user is the
    superuser.         

 hmm.. off to ruserok(3)...

    machine name is listed in the ``hosts.equiv'' file, or the host and re-
    mote user name are found in the ``.rhosts'' file; otherwise iruserok()

 and examining /usr/share/skel/dot.rhosts (the template for .rhosts)

#       $Id: dot.rhosts,v 1.3 1996/09/21 21:35:47 wosch Exp $
#
# .rhosts - trusted remote host name and user data base
#
# see hosts.equiv(5), rsh(1), rlogin(1), rcp(1)
#
# This file should NOT be group or other readable.
# OtherMachine
# OtherMachine myFriend      

 so I guess its there.. just a bit hidden and not too clear....

 If your having some problems you can't figure the process for
 authenticating is spelt out in the rshd/rlogind man pages, and
 the code for the ruserok function is in 
 /usr/src/lib/libc/net/rcmd.c
