Hi there. Is there a howto move from hdb to mdb?
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
Thank you in advance

Currently I have done the following:
- Load the Module back_mdb
- Created a OlcBackend
- 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.
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 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.

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.

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. Do you know a good policy for increamental backup? I mean i only have now 10000 users but in the future it will really get bigger and i hate to dump the whole database every night.

Hi,
Do you know a good policy for increamental backup? I mean i only have now 10000 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.

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?
