0) Make sure every time you restart /etc/init.d/ldap.client
(ldap_cachemgr), restart also the /etc/init.d/nscd (name service cache
daemon).
1) Make sure you define "CRYPT" as the default passwordStorageScheme in
LDAP DIT (right click cn=config and edit its properties).
2) Make sure you have these three lines in /var/ldap/ldap_client_file
and also in "default" profile in LDAP DIT?
NS_LDAP_SERVICE_SEARCH_DESC= passwd:
ou=People,dc=composers,dc=foo,dc=com?one
NS_LDAP_SERVICE_SEARCH_DESC= group:
ou=group,dc=composers,dc=foo,dc=com?one
NS_LDAP_SERVICE_SEARCH_DESC= shadow:
ou=People,dc=composers,dc=foo,dc=com?one
And there is a "shadow: files ldap" line in /etc/nsswitch.conf.
3) Make sure you restart SSH Server whenever there is a change in
/etc/ssh/sshd_config.

4) Did you install a binary version of OpenSSH Server with PAM support
or compile from source with an "./configure --with-pam" option?
To check if sshd is built with PAM support, run:
# ldd /usr/local/sbin/sshd
It should have something like "libpam.so,1" in it:
libpam.so.1 => /usr/lib/libpam.so.1
libdl.so.1 => /usr/lib/libdl.so.1
libresolv.so.2 => /usr/lib/libresolv.so.2
libcrypto.so.0.9.7 => /usr/local/ssl/lib/libcrypto.so.0.9.7
librt.so.1 => /usr/lib/librt.so.1
libz.so => /usr/lib/libz.so
libsocket.so.1 => /usr/lib/libsocket.so.1
libnsl.so.1 => /usr/lib/libnsl.so.1
libc.so.1 => /usr/lib/libc.so.1
libcmd.so.1 => /usr/lib/libcmd.so.1
libgcc_s.so.1 => /usr/local/lib/libgcc_s.so.1
libaio.so.1 => /usr/lib/libaio.so.1
libmp.so.2 => /usr/lib/libmp.so.2
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1
5) The output of your "sshd -d" looks perfectly fine and it isn't what
you said "totally silent", the SSH Server is listening, as and when you
perform ssh connection from any host to the ssh server, you would see
more "debugging" messages appearing in this "interactive" mode, to exit,
press Ctrl-C to kill the debugging mode, note that after this sshd is no
more running.
6) For ssh client connection, do this way to see more:
$ ssh -v testdba at 192.85.86.87

Gary, here's the output from /var/adm/messages:

What does that mean? I took the pam.conf from the website you gave me
and commented out the lines, like you said:
login auth requisite pam_authtok_get.so.1 debug
login auth required pam_dhkeys.so.1 debug
#login auth required pam_unix_cred.so.1 debug
login auth required pam_dial_auth.so.1 debug

Also:
bash-2.03# getent passwd testdba
testdba::10001:7000::/home/testdba:/bin/bash
sshd -d is totally silent. No output after startup:

Yep, changed that!
Still (from the remote machine):
cnyitsun01/ > ssh testdba at 192.85.86.87
Password:
LDAP Password:

And it never lets me in.
