quanah,

Thanks for your reponse. maybe I didn't specify case clearly.

we backup the files. then we have to do full installation of the sytem (with new release), in this new installation, we had new data created in openldap during the installation. then we manually restore the data with sldapadd, and the new data creaetd during the full installation was lost because of the old backup file don't include these new data created during full installation.

We tried to with "-c" option to run slapadd, but it still return error result:

like the following code. the slapadd report some entries already exist, then the final result of slapadd is 1 (failure).

slapadd -c .....

if [ $? != 0 ]; then

// print error and exit.

fi

Is it possible that we ingore the existing entry and slapadd return 0 or some meanful result finally?

Thanks,

Eric.

All,

I got one question, when doing openldap restore, in our script, we tried to remove the openldap/data directory, then restore the backup openldap files.

but since we have other data added in openldap database after backup. then if we doing backup, it will remove the data newly added after backup.

Stop slapd, take a new slapcat, then restore...

Quanah,

All,

So openldap can't skip to add the entry if there is already an existing entry? in other database, the insert operation will check the entry exists or not. if exist, do nothing. if not exist, then insert it. there are other operation like insertupdate.

do we have any option to skip the existing entry?

Thanks,

Eric.

Sounds like you should restore the backup file as part of the new full installation as one of the first steps. That's what we do with Zimbra.

Quanah,

Thanks for your response! I got it.

but why openldap will not skip the insert when the entry already existed. I found some code in openldap already handle like this, anyway, it could take some effort.

rc = mdb_cursor_put( mc, &key, data, MDB_NODUPDATA|MDB_APPEND|MDB_MULTIPLE ); if ( rc ) { if ( rc == MDB_KEYEXIST ) { rc = 0; continue; } rc = -1; break; }

Thanks,

Eric.

slapadd is a tool used for BULK RESTORATION of the ENTIRE DB. You can skip using -c, but it will skip ALL errors. You are *not* using the right tool for what you are attempting to do.

If you want to do something else, try the ldapdiff utility (http://www.openldap.org/faq/data/cache/612.html) and use that to diff your current db and your backup, and then use ldapadd to add the missing entries.
