Configuring MirrorMode via cn=config

[Pavlos Parissis <p_pavlos@freemail.gr>]

Hello all,

I am writing to ask for a confirmation on the steps that I followed to
configure MirrorMode replication via cn=config

The step is the typical, 2 nodes where m1 is the first node and m2 is the second one.

1) start m1
2) create dit 
3) add mirrormode_user
4) slaptest -f slapd.conf -F slapd.d
   chown -R ds-ldap.ds-ldap slapd.d 
5) stop m1 ;start m1
6) enable sync log
7) start m2
8) slaptest -f slapd.conf -F slapd.d
   chown -R ds-ldap.ds-ldap slapd.d
9) stop m2;start m2
10) enable sync log
11) add replication configuration on m1 [1]
12) add replication configuration on m2 [2]


I did testing on the replication and it worked.

But, I noticed that when I configured the syncpro overlay after the replicas both servers stopped responding.
I will try to reproduce that issue and get some debug messages, may be I didn't something wrong or it is a bug.

Cheers,
Pavlos
