This shouldn happen, slapcat (8) manpage tells: "For some backend types, your slapd(8) should not be running (at least, not in read-write mode) when you do this to ensure consistency of the database. *It is always safe to run slapcat with the slapd-bdb(5)*, slapd-hdb(5), and slapd-null(5) backends." So using ldapsearch is more reliable for me ... Kindly regards Meike

Any issue on random OIDs?
by Geo P.C. 31 May '13

31 May '13

For our openldap server we created custom attributes by giving random OIDs like 2.25.10.1, 2.25.10.100.10 etc . We are able to add custom attributes and the LDAP server is working fine. Please let us know is there any issue in giving random OIDs for attributes and object classes. Also is there any issue in future while using this. Can anyone please advise us on this. Also I came to know that we can create OIDs without registering. From this site http://www.itu.int/ITU-T/asn1/cgi-bin/uuid_generate I can create UUID but from where I can convert this UUID to OID? Suppose when we convert this UUID to decimal shall we can use it permanently without any issue? Please help us on it Thanks Geo* <http://pcgeo.blogspot.in/>*

I compared it and found this three additional attributes are in the ldapsearch, but not in slapcat: - entryDN - subschemaSubentry - hasSubordinates It seems, that slapcat ignores this values or at least, it does not complain...

But I saw, that a ldapsearch ldif with operational attributes has a more operational attributes than from the slapcat ldif. Is it possible with this ldif, to create the database like my colleague it used? Thanks Meike

Post-clone Cleanup of Hostname on Version Query
by Kim, Robert 31 May '13

31 May '13

I've been cloning servers with LDAP server set up on them and the process has been working fine but when I recently queried the version with slapd -V, the hostname of the original server shows up. I tried re-running make and make install with no luck. How can I change the hostname that shows up on the version query without redoing the whole installation?

Re: how to take hot backup of MDB ...
by anil beniwal 30 May '13

Hi Sanjay e.g /opt/symas/bin/mdb_copy /openldap-data /backup/ syntax:- mdb_copy /<db-dir> /<backup destination> You only need data.mdb file. We are having very big db size(about 500Gb) and we never face any problem with backup. lock.mdb is not required. You can simply copy back data.mdb to your db directory for restoration and it will work like magic.

by Meike Stone 30 May '13

Hello, is it possible to use a ldif-backup with operation attributes (ldapsearch ... '+' '*') with slapadd, to save the operation attributes, if no slapcat backup is available? Are there any concerns? Thanks Meike

how to take hot backup of MDB ...
by Sanjay Jain 29 May '13

29 May '13

Hi, I have a server that runs on top of MDB. While provisioning is going on, I would like to take the backup of MDB (data.mdb and lock.mdb files). While trying to use mdb_copy command line tool, I noticed: - mdb_copy utility hangs while server is up, I guess waiting for a lock (on DB?) to be released by the server. - if I shutdown the server, mdb_copy works but copies only data.mdb and NOT lock.mdb How do I take backup of data.mdb and lock.mdb files while server is up and provisioning is going on? Is mdb_copy not the right tool for this purpose? What am I missing? Thanks, Sanjay
