Ubuntu 16.04 Build OpenLDAP from source

Question

I want to enable slapd feature --enable-spasswd. So I download OpenLDAP source code from this url.

http://mirror.eu.oneandone.net/software/openldap/openldap-release/openldap-2.4.44.tgz

Then I run configure with the following parameters.

./configure \
    --prefix=/usr \
    --libexecdir=/usr/sbin \
    --sysconfdir=/etc/ldap/ \
    --localstatedir=/var/run \
    --datarootdir=/usr/share \
    --datadir=/usr/share/slapd \
    --disable-ypt \
    --enable-modules \
    --enable-rlookups \
    --enable-overlays \
    --with-tls \
    --disable-sql \
    --with-system-libtool \
    --disable-ltdl-install \
    --enable-spasswd \
    --with-cyrus-sasl \

Once the build completed and then start the OpenLDAP process by this command. But the process exit immediately. After that, I tried to diagnostic the problem by strace.

unlink("/var/run/run/ldapi")            = -1 ENOENT (No such file or directory)
umask(0)                                = 022
bind(8, {sa_family=AF_LOCAL, sun_path="/var/run/run/ldapi"}, 110) = -1 ENOENT (No such file or directory)

My question is, how is the slapd package being configured in Ubuntu 16.04. Is it possible to read the Makefile that is used to build the apt package?

Answer 1

Finally, I found out that I can get the source apt-get source and debuild. And by that, I learned the slapd in debian package has all the options enabled.
