Issue with edge integration with read only AD

Hi,

We are using subversion edge(1.3.2) integrated with AD. Earlier, edge server was placed in the same subnet as that of writeable AD and 135, 389 and 3289 ports were open. This setup is working perfectly fine.
Now due to some security constraints, we are implementing the following architecture
                                Edge --> Read only AD --> Firewall -->Writeable AD
Edge and ROAD in development subnet and writeable AD is in the production subnet. The same ports are opened between edge and ROAD. But the setup is not working. PFA the server logs. Can you please help us regarding this.

Thanks,
Hima
