Full_Name: Frank Offermanns Version: 2.4.21 OS: Windwos URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (217.6.189.242) I am running LDAP from Head with BDB 4.8.26 as backend on windows. I am testing master/slave replication while adding 10000 users with 10 filled attributes. I am not using a specific time synchronization. Standard windows time synchronization in domains is active. But as far as I understood, a microsecond time synchronisation is only needed for master-master, which I am not testing.
