Hi,
One trick you could do, but really risky and may render your sshd 'unstable', is to use an hexeditor and look for the pattern then apply the change ...
But, if its for security reason, people tend to think such modification is futile and will give you no more safety since most "proggies" will always try to
test your installation

ssh-ldap-helper
SSH-LDAP-HELPER(8) BSD System Manager's Manual SSH-LDAP-HELPER(8)
NAME
ssh-ldap-helper -- sshd helper program for ldap support
SYNOPSIS
ssh-ldap-helper [-devw] [-f file] [-s user]
DESCRIPTION
ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP. ssh-ldap-helper is disabled by default and can only be enabled in the
sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''.
ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper.
The options are as follows:
-d Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog.
-e Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file.
-f ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default).
-s ssh-ldap-helper prints out the user's keys to stdout and exits.
-v Implies -d; increases verbosity.
-w ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file.
SEE ALSO
sshd(8), sshd_config(5), ssh-ldap.conf(5),
HISTORY
ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP .
