[K12OSN] Using replication

My Replication server is working I have a Master-Slave LDAP server, But it
is still not a failover. I shutdown my Master server, and attempted to login
to a windows XP client, and it did not work. 
I know replication is working because I modified a users name and then did
an ldapsearch on the slave server ,and the changes where there.

My pointer in to making a slave server, flow link to the directions posted
by Brian, make sure when you do:
Bindmethod=simple -- do not leave spaces. 
You can either copy your lidif file into the new server or copy the entire
directory /var/lib/ldap to the slave server then make sure to change
ownership
Chown -R ldap:ldap /var/lib/ldap

On the Master server you can kill the ps for the  ldap server, then restart
the service. You can run slurpd -f /etc/openldap/slapd.conf, to check for
any replication errors.

These are things just to lookout for.

When I start my ldap service on the slave server, the slapdis the only one
the start, on my master server the slapd and slurpd start, Is this correct,
should the slurpd start on the slave as well?

I've followed the instructions on 
http://k12linux.mesd.k12.or.us/ldap/high_availability.html to setup a 
master & slave ldap servers for replication but I'm having a problem 
with the readonly option.

If I set this option to on, in the slave config the replication doesn't 
work and I get an error in the log on the master.

Is it possible to run the slave in readonly mode but still have 
replication working, I'm using the rootdn to bind with so I thought this 
would override the readonly option.

Has anyone setup ldap replication ?
