Hello,
thanks for the slapd mirror idea it's works but I hava got one problem,
when one server stop I can continue to add information in the first one,
and when the second server failback It doesn't resync data automaticaly.
I have to manualy done that :
crn node standby ldap01-server
cd /var/lib/ldap
rm -rf __db.00* log.* *.bdb
crm node online ldap01-server
Sincerely
