Unable to load the lastbind module with 2.4.44 (custom build)

[mailing lists <listas.correo@yahoo.es>]

Hello all,

What I'm trying to do is enable the lastbind module in a centos7 server, so I applied this patch to the rpmbuild process:

the resulting package contains the module:

# rpm -qpl /root/rpmbuild/RPMS/x86_64/openldap-servers-2.4.44-1.x86_64.rpm | grep lastbind
/usr/lib64/openldap/lastbind-2.4.so.2
/usr/lib64/openldap/lastbind-2.4.so.2.10.7
/usr/lib64/openldap/lastbind.la
/usr/share/man/man5/slapo-lastbind.5.gz

but a configuration file as simple as the following one, fails to load:


# cat test.conf

any idea about where I make the mistake?
