Solaris logs - Tracking failed attempts from my host

Hey all I'm having a big problem here. Someone is attempting an SSH to a destination host on which an account resides and locking the account. I'm trying to determine who is performing the SSH attempts from my host. For instance they're logged in as their standard account but then (I'm assuming) they're performing something like:

Code:

ssh locked_account@destination_host

where locked_account is the system account in question and after 9 tries with the wrong password it locks the account on the destination host. We know the failed attempts are coming from my host but not sure who is executing that command.

I checked /var/adm/sulog which doesn't show anyone performing su access to this system (functional - it's not bin or sys or anything like that) account. Is there a way to determine if someone executes the aforementioned SSH attempt? I was thinking their bash_history but some are using ksh and don't have history enabled. I'm using SunOS 5.10.

ssh-keysign

SSH-KEYSIGN(8)						    BSD System Manager's Manual 					    SSH-KEYSIGN(8)

NAME

     ssh-keysign -- ssh helper program for host-based authentication

SYNOPSIS

     ssh-keysign

DESCRIPTION

     ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
     SSH protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
     EnableSSHKeysign to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).  See ssh(1) and sshd(8) for more information about host-based authen-
     tication.

FILES

     /etc/ssh/ssh_config
	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to generate the digital signature.  They should be owned by root, read-
	     able only by root, and not accessible to others.  Since they are readable only by root, ssh-keysign must be set-uid root if host-
	     based authentication is used.

SEE ALSO

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

HISTORY

     ssh-keysign first appeared in OpenBSD 3.2.
