Ability to start (or convert) database to MDB

[JohnOmernik]

Two things, starting from scratch and using MDB files (for performance) and the option to move current HDB setups to MDB.

Thoughts?

if someone can explain how to move HDB setup to MDB it would be great :)

Did you found solution for this? I too need to do migration from HDB to MDB

[JohnOmernik]

I am still looking for a sane way to do it. Most of the guides I've found require much more OpenLDAP knowledge than I currently have. If i get steps I will post here.

So I converted, now I have a smaller setup, so it may have been easier for me, but here are my steps:

• Update start file (script that runs openldap in docker) to include env varable LDAP_BACKED: mdb
• Go to current host running openldap, docker exec /bin/bash into it
• run: slapcat -v -l /path/to/external/volume/dump.ldif you need to take this data out of the contianer, so make sure it exists after shutting down!
• Then copy dump.ldif as a a saved copy (dump_saved.ldif or something)
• Stop current openldap docker
• cp -R ldap and slapd.d volumes (your external data) to ldap_hdb and slapd.d_hdb
• mv ldap to ldap_old and slapd.d to slad.d_old
• mkdir ldap and slapd.d (new empty directories)
• Start openldap fresh, it will create a blank DB with your settings (including setting up the core dn, admin, and readonly if set)
• edit dump.ldif to remove the first three entry blocks (dn for your base, then admin@ and readonly@ if they exist)
• Go to host running open ldap, run slapadd -l /path/to/dump.ldif (inside of container that runing openldap)
• Now you should be good to go!

I then created indexes everything seems to be working!

HI, John:

thank you for your procedure, I am converting bdb to mdb now.

I have difficulty to understand your step 6 -9.
cp -R ldap and slapd.d volumes (your external data) to ldap_hdb and slapd.d_hdb
mv ldap to ldap_old and slapd.d to slad.d_old
mkdir ldap and slapd.d (new empty directories)

Do you mean I need rename my volumes to ldap_hdb and slapd.d_hdb ? I got very confused here.
I have created two volumes as "ldap" and "slapd.d" and mounted them into /var/lib/ldap (LDAP database files) and /etc/ldap/slapd.d (LDAP config files). Do I need rename the volume or do something ?

Please help.

so long ,but I search aroud, and no answer,so paste my steps here:

step 0: prepare hdb backup file: ldap-2020-03-03.ldif

mkdir -p /test/openldap/backups
cp -v ldap-2020-03-03.ldif /test/openldap/backups
tree openldap/
openldap/
└── backups
└── ldap-2020-03-03.ldif

step 1: generate config files

docker run
--name openldap
--env LDAP_TLS=false
--env LDAP_ORGANISATION="baidu"
--env LDAP_DOMAIN="baidu.com"
--env LDAP_ADMIN_PASSWORD="yourpassword"
-p 389:389
-v /test/openldap/config:/etc/ldap/slapd.d
-v /test/openldap/backups:/backups
-d osixia/openldap:1.3.0

docker stop openldap && docker rm openldap

│   └── olcDatabase={1}mdb.ldif
├── cn=config.ldif
└── docker-openldap-was-admin-password-set

step 2: import backup data

docker run --rm
--name openldap
--env LDAP_TLS=false
-p 389:389
-v /test/openldap/database:/var/lib/ldap
-v /test/openldap/config:/etc/ldap/slapd.d
-v /test/openldap/backups:/backups
-d osixia/openldap:1.3.0 bash -c "slapadd -l /backups/ldap-2020-03-03.ldif"

│   ├── cn=config.ldif
│   └── docker-openldap-was-admin-password-set
└── database
├── data.mdb
└── lock.mdb

step 3: finally,fire openldap

docker run
--name openldap
--env LDAP_TLS=false
--env LDAP_ORGANISATION="baidu"
--env LDAP_DOMAIN="baidu.com"
--env LDAP_ADMIN_PASSWORD="yourpassword"
-p 389:389
-v /test/openldap/database:/var/lib/ldap
-v /test/openldap/config:/etc/ldap/slapd.d
-v /test/openldap/backups:/backups
-d osixia/openldap:1.3.0

step 4:tested

test with confluence, works fine
