I’m currently trying to setup datagerry on 3 cluster nodes, with a Mongodb Replicaset underneath.

I’ve seen that the latest RC supports to override a CONNECTION\_STRING environment variable, which I filled with the Replicaset:  
Currently running becongmbh/datagerry:latest (image id 179f18e01d60) against mongodb/mongodb-community-server.

```auto
    "Env": \[
        "CONNECTION_STRING=mongodb://datagerry:somepassword@10.XX.XX.1:27017,10.XX.XX.2:27017,10.XX.XX.3:27017/?replicaSet=rs0",
        "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",

```

Given the fact that the application could initialize the CMDB DB and I’m able to connect to the RS via cmdline, I assume that would technically be working.

I see the datagerry UI, but I can’t login with the initial admin/admin Account. This is what I see on the UI:

Any pointers?
