olcMirrorMode attribute in N-way multimaster

Hi all,

I'm working on an multimaster setup using the LDIF configuration (as opposed to slapd.conf). From my understanding of the documentation, Mirror Mode is distinct from N-way Multimaster in that it is an 'active-active/hot swap' configuration, and writes need to go a single server.

In the admin guide's example found here:

http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master

the N-way multimaster has this attribute set:

add: olcMirrorMode olcMirrorMode: TRUE

Could someone clarify what the olcMirrorMode attribute is for in the N-way multimaster configuration?

Thanks for your help in advance, Chris
