I tried following and is able to install it in my Home directory.

./configure --prefix=/my/home/directory/parveen/OpenLDAP_LMDB --exec-prefix=/my/home/directory/parveen/OpenLDAP_LMDB --enable-bdb=no --enable-hdb=no

make depend

make

make test

make install

make test -->Shows some error, but not finally. Will do it again and capture the logs and check what was errors.

However I am a bit confused about following steps in guide.

2. A Quick-Start Guide

9. Import the configuration database

You are now ready to import your configration database for use by slapd(8), by running the command:

su root -c /usr/local/sbin/slapadd -F /usr/local/etc/cn=config -l /usr/local/etc/openldap/slapd.ldif

10. Start SLAPD.

You are now ready to start the Standalone LDAP Daemon, slapd(8), by running the command:

su root -c /usr/local/libexec/slapd -F /usr/local/etc/cn=config

What is "/usr/local/etc/cn=config"?

And when I am making an Organization Unit entry I get error.

575529e7 mdb_dn2entry("ou=Comp1,dc=Domain,dc=com")

575529e7 => mdb_dn2id("ou=Comp1,dc=Domain,dc=com")

575529e7 <= mdb_dn2id: get failed: MDB_NOTFOUND: No matching key/data pair found (-30798)

575529e7 mdb_add: parent does not exist

575529e7 send_ldap_result: conn=1000 op=3 p=3

575529e7 send_ldap_result: err=10 matched="" text=""

575529e7 send_ldap_response: msgid=4 tag=105 err=32

Probably some small mistake in configuration or addition of entry, but not able to find now.

Can you provide some pointers?

Or it is like that we have completely done away with Berkley DB and now we should use LMDB preferably.

If so, can you provide the link for deploying the same, like How to Compile and install.

Hello All,

We are using OpenLDAP 2.4.44 in our project, but facing a dilemma over the Berkley DB version.
Which version we should use or it is not required at all now as we have LMDB.
Moreover Oracle has removed some links for downloading the older Berkley DB version.

OS : RHEL
cat /etc/redhat\-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)

I referred the Online guide, but was not able to conclude.
4.2.4. Database Software
OpenLDAP's slapd(8) MDB primary database backend uses the LMDB software included with the OpenLDAP source. There is no need to download any additional software to have MDB support.
OpenLDAP's slapd(8) BDB and HDB deprecated database backends require Oracle Corporation's Berkeley DB. If not available at configure time, you will not be able to build slapd(8) with these deprecated database backends.
Your operating system may provide a supported version of Berkeley DB in the base system or as an optional software component. If not, you'll have to obtain and install it yourself. Berkeley DB is available from Oracle Corporation's Berkeley DB download page if required.
There are several versions available from Oracle Corporation. Berkeley DB version 6.0.20 and later uses a software license that is incompatible with LDAP technology and should not be used with OpenLDAP.
Note: Please see Recommended OpenLDAP Software Dependency Versions for more information.
