building une 2.3

[De Leeuw Guy <G.De_Leeuw@eurofer.be>]

Hello
I just build the openldap-2.3.11.
I try to build my program now and I receive these errors :

../src/gdLdap.c:43: error: `ldap_init' undeclared (first use this function)
../src/gdLdap.c:50: error: `ldap_open' undeclared (first use this function)
../src/gdLdap.c:57: error: `ldap_unbind' undeclared (first use this 
function)
../src/gdLdap.c:69: error: `ldap_init' undeclared (first use this function)
../src/gdLdap.c:86: error: `ldap_bind_s' undeclared (first use this 
function)
../src/gdLdap.c:645: error: `ldap_add_s' undeclared (first use this 
function)
../src/gdLdap.c:647: error: `ldap_modify_s' undeclared (first use this 
function)
../src/gdLdap.c:854: error: `ldap_search_s' undeclared (first use this 
function)

I check the ldap.h and I see that this functions are deprecated.
But where I find documentation to adapt my program ?
I check the man pages but without succes.

Thanks in advance

Guy
