Sun LDAP server on Solaris 10 compared to Solaris 8

Hi,
i have one application, designed for Solaris 8 which I would like to install
on Solaris 10. Application ships with sun Directory server/ldap that needs
to be installed first (old 5.x DS).
Old DS expects system library libldap.so.3 (which is present on Solaris 8)
and libldap.so.4 is installed on Solaris 10. I also think that they reside
in different direcotry (I don't have server in front of me, I am writing
this by memory).
First, I am not sure if ldap server comes preinstalled on Sol10, or one
needs to install it.
My question is: what would be recommended way of using Sun ldap on Solaris
10:
-either to install old DS (which is accompanying that application) on Sol10
and then tweak with libraries, link libldap.so.4. to a fake name
libldap.so.3 or similar ...
-or download and install new DS ? I am afraid that there is some differences
in ldap versions which could break that application.

thanks,
jmiklo
