that could be fine, but I have already samba installed in /opt and I
would like to install side-by-side samba3 and samba4.

But I understand it takes a lot of time to debug my faulty installation.

In a working install, where is located ldapsam backend lib? ($PREFIX/lib)

thank you again,

Francesco

To what end? you cannot run two instances of samba at the same time 
without jumping through hoops.

What is wrong with your existing installation ?

It is where ever your installation of openldap puts it, from memory on 
wheezy it is likely to be /var/lib/ldap, but you need something to read 
it, ldapsearch, LAM or similar.

A Debian install is going to put directories, executables and state file
all over file system. A custom install with $PREFIX=/opt/samba4 is
easier to match with the current running installation of samba3 which is
in /opt/samba

What was faulty was my compilation of samba4 which lacked ldapsam support.

Actually it was a stupid mistake. Sometime in the past I added
/opt/samba/lib (the samba3 install directory) to the ldconfig.
Removing that directory, samba4 compiles, make and installs fine with
ldapsam.

thank you,

Francesco
