Hello!

I've implemented a simple openldap master and consumer architecture. To achieved this, I had to implement back-ldap chain overlay (in order to have a read only "slave"), and syncprov overlay, to synchronize data from master to the slave.

This implementation works fine. I have data from the master, replicated into the slave. When I try to modify an object from the consumer using the administrative account "cn=admin,dc=company,dc=com", references the modify command to the master. The master performs the operation and returns the consumer the operation result.

When I try to perform any modify operation with another authorized account, I get the following error

*LDAP said*:Proxied Authorization Denied*Error number*:0x7b ()*Description*: The account has permission to write the whole tree in both, the master and the slave. Here is my config on both servers:

Hope someone can help me out! Thanks in advanced
