Re: Antw: Mirror mode not working with other user accounts

Hi Ulrich,

Thank you. I'll have a look into this. Apologies, but I'm new to OpenLDAP and learning as I go, and I must admit that everything below was taken from a number of different tutorials on the subject of mirroring an OpenLDAP server. Admittedly, no tutorial on the subject was perfect, especially since most were written using slapd.conf, and the install I'm using doesn't use that config method, so I've had to learn a lot by trial and error to get the mirror mode to where it is now, learning a lot about ldif syntax along the way.

I did wonder why the syncrepl command was only mirroring the config database, but not knowing any different, I deferred to the knowledge contained within the tutorials, and the mirror worked perfectly when using the manager account to add, modify, or delete any data, on either server, so I gave no more thought to it when it didn't work under any of the accounts I created to specifically manage an OU each, thinking the sync was working perfectly, and that the fault must lie somewhere in the user ACLs.

I'll have a read up on syncrepl, and what else I need to sync, to get this working.

Cheers,

Mark

From the data I see that you mirror cn=config, but what about the rest?
