How to set BDB "read-only" before slapcat command ?

[Andrew Hall <whippyhubbles@googlemail.com>]

Hi there.

According to this doc...

http://www.openldap.org/doc/admin24/maintenance.html#Directory Backups

Prior to slapcat being used for a backup the DB should be set to read-only.

How exactly is this done ?

I am using a BDB backend and all I can find is in this doc...

http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/archival.html

Which also doesn't describe how.

Is there an OpenLDAP or BDB command / tool which I can use to do this ?

Thanks very much.
