I did things the opposite way round:

1. slapcat your data database
2. slapcat your config database
3. Modify the generated config database ldif to correspond with that of
an mdb database i.e. change the objectclass, remove any bdb-specific
configuration, add the mdb specifics (MaxSize, maxReaders etc- there's a
lot less tunables in mdb)
3. Stop slapd and move your "old" config aside
4. slapadd your new config database
5. If 4 is successful, move your data directory aside and
6. Slapadd your data ldif.
7. Go for a (short) cup of tea
8. Fire up slapd.

Ok. Maybe you are right. Sometimes "Less is more".
I am moving forward to high availability and i am planning to set two ldap
servers in Mirror mode.
I have already setup a haproxy in front but i have two problems.

1. Not able to enable StartTLS (currently only SSL is functional)
2. It seems quite slower. Is this normal?

Hi,


Do you know a good policy for increamental backup? I mean i only have
now 1 users but in the future it will really get bigger and i hate
to dump the whole database
every night.


Why not? I'm dumping our directory with 70.000 entries using slapcat 
every night in less than a minute.

Thank you Oscar.
Dan also provided a good solution. I think both of them work like a charm.
The problem for me is that i wanted to do it all in a GUI (Apache Directory
Studio) which messes up with backend and database or even object indexes.

Anyway now i managed to do that using slapxxx and old good ldapmodify.
Thank you a lot.

Re: How to move from hdb to mdb

[Nikolas Stylianides]

Thank you Dan.
I tried to do that but it took me like forever. I am using Apache Directory
Studio and doing modifications from this tool really gave big headaches.
Is there a better tool to manage both config and the databases?

I see no problem to have them on different servers.
You can set a new server with mdb backend, import a dump (slapcat(8) +
slapadd(8)) and start replicating from your actual servers.

And then, after some testing, you can make the switch between servers.

Hi there.

What we need to do is to transfer our directory from hdb to the mdb.
Is there a book to learn about openldap? With the new OLC way of doing
things?

Can i have hdb and mdb running at the same time?

Currently I have done the following:
1. Load the Module back_mdb
2. Created a OlcBackend
3. Created a OlcDatabase


See http://www.openldap.org/doc/admin24/ and slapcat(8), slapadd(8),
slapd-mdb(5), and slapd-config.

Consider converting in two steps - converting your database to mdb first,
then converting to slapd-config.
