I recently upgrade from source and this is my procedure. Your's will certainly be different, but it gives you the basic steps.

First check to make sure we have an LDIF backup of entire LDAP database.

1. install new openldap

cd /usr/local/src wget ftp://ftp.openldap.org/pub/OpenLDAP/openldap-release/openldap-2.4.42.tgz tar zxvf cd openldap-2.4.42 ./configure --enable-bdb=no --enable-hdb=no --enable-mdb --with-tls=openssl --with-cyrus-sasl --enable-spasswd --enable-syslog --enable-modules --enable-cleartext --enable-overlays --enable-accesslog --enable-auditlog --with-threads --enable-shared --enable-ldap --enable-monitor --enable-deref --enable-slapd --enable-ppolicy --enable-memberof make depend make make test make install <-- be careful after this point, as a "slapd restart" will then use the new code. Must complete step 2 before restarting slapd.

2. copy our custom schema files to new scheme directory cd /usr/local/etc/openldap cp custom_schema_files/* schema/

3. start new slapd

/etc/init.d/slapd stop *** to stop currently running old version*** /etc/init.d/slapd start *** new version***

if things go badly revert by going to previous /usr/local/src/openldap directory and doing a make install

/usr/local/src/openldap-2.4.xxx

check schema files and restart slapd

Hi all,

I'm starting as an openLDAP administrator, and here in my company they are running the openLDAP 2.4.35.

• I found this avec la commande ldapsearch -VV

I want to upgrade to the letest version available (2.4.42), how should I procede ?

I read that I just need to download the new package, stop the server, install the new version and then restart the server, is that all?

Thanks in advance for your help, Marc
