Re: *****SPAM***** openLDAP replication and trigger a script or exec binary
--On Saturday, March 10, 2007 3:02 AM +0800 "Ivan R. Sy Jr."
I seem can't find a way to allow OpenLDAP to execute a shell script or
exec binary whenever it gets modified by slurpd.
My agenda is to have master->slave LDAP replication and when the slave is
modified via slurpd, it will then execute something (shell
script/binary/anything) from the system and then resumes normal operation
(returning success code to slurpd)
Here's what i understand with openLDAP replication:
Step 1: An LDAP client starts up and connects to a master /slapd/.
Step 2: The LDAP client submits an LDAP modify operation to the master
Step 4: The master /slapd/ performs the modify operation, writes out the
change to its replication log file and returns a success code to the
Step 5: The /slurpd/ process notices that a new entry has been appended
to the replication log file, reads the replication log entry, and sends
the change to the slave /slapd/ via LDAP.
Step 6: The slave /slapd/ performs the modify operation and returns a
success code to the /slurpd/ process.
in step6, is there a way that slapd performs the modify operation... and
"execute a shell script or binary and when it exists", it returns a
success code to slurpd process?
maybe a patch somewhere? or a clue where to set this hook? or any light
I would use OpenLDAP 2.3, set up an accesslog for the database, and then
have a process that "listens" to changes made to the accesslog, that can do
whatever it is you want done when changes are made.
