Code:
$ ssh host1 'test -e /etc/resolv.conf' ; echo $?
0
$ ssh host1 'test -e /etc/resolv.confa' ; echo $?
1
$ ssh host1a 'test -e /etc/resolv.conf' ; echo $?
ssh: host1a: Name or service not known
255
$ ssh host1a 'test -e /etc/resolv.confa' ; echo $?
ssh: host1a: Name or service not known
255
$ ssh user@host2 'test -e /etc/resolv.conf' ; echo $?
ksh: test: argument expected
1
$ ssh user@host2 'test -f /etc/resolv.conf' ; echo $?
0
$ ssh user@host2 'test -f /etc/resolv.confa' ; echo $?
1

OpenSSH always passes back the return code of the command, your only problem might be if the command returns 255, since that would make it difficult to discern between an SSH error and an application error.

Maybe your hosts' test command doesn't know about the -e switch. Use -f instead (which doesn't check for existence but whether it's a file or not. Will fail on directories)

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 .
