[SOLVED] Re: replication security (i)
ah yes i've done it now. thought i'd post my results in case any other ldap newbies have a similar problem. :-)
the problems with my setup stemmed from not setting up a dedicated replication account with access to the slave database. i had to create a replicator account and give that full access to the slave, removing the existing acls, ie.
access to *
by dn="uid=replicator,ou=users,dc=my,dc=local" write
by * read
my master server also had a 'syncrepl' entry (which i probably added in a moment of desperate frustration) and it wasn't needed in this case.
thank you everyone who helped me out!

<br>thanks for replying.<br><br>that makes sense. let me see if i have the logic right.<br><br>the reason my updates are being processed on the slave is because i'm not using a specific replication account as my updatedn. i am in fact using the manager dn, which explains why updates to it are being accepted when i connect directly to the slave with the manager's credentials.<br><br>presumably then i need to change my slave acls to allow only the replication account write access, which will force any update requests to be handed up to the master.<br><br>if that is right then the reason i confused the issue was to simply copy the config file from the master to the slave without setting separate acls on it.<br><br>john<br><br> --- On Thu 11/10, Buchan Milne < email@example.com > wrote:<br>From: Buchan Milne [mailto: firstname.lastname@example.org]<br>To: email@example.com<br> Cc: openldap-software@OpenLDAP.org<br>Date: Thu, 10 Nov 2005 19:03:45 +0200<br>Subject: Re:
