Dear All,

               I am using openldap-2.4.11 version and trying to use N-way multimaster replication so that changes made to first server reflects to second and vice versa but with my current set up if i use syncprov overlay and syncrepl on both server then it doesn't allow me to make changes in any ldap server but if i configure syncprov overlay on one server and configure syncrepl on another server it allow me to make changes and as well reflect the changes to another however still i can't make changes to second ldap server my both server configuration is as follows. please let me know what is wrong with this configuration or what all changes to be made to running it.
