## Edit the two zcash.conf files
There are two zcash.conf files; one read by zcashd, one read by lightwalletd.
### `$ZCASHD_DATADIR/zcash.conf` -- read by zcashd
### `$ZCASHD_DATADIR/zcash.conf`—read by zcashd
The zcashd's `zcash.conf` needs to look like:
```
rpcuser=zcashrpc
rpcpassword=Z7V7IoXt6I0OVuKr7TpHjxAnE6NvB/ZBRdM6x9w/OAU=
rpcpassword=TODO INSERT A RANDOM PASSWORD HERE
experimentalfeatures=1
lightwalletd=1
```
Replace `TODO INSERT A RANDOM PASSWORD HERE` with a random password, e.g. the output of `head -c 16 /dev/urandom | base64`.
`rpcuser` and `rpcpassword` must be set, as lightwalletd doesn't work with RPC cookies (see the [rpcpassword](https://zcash.readthedocs.io/en/latest/rtd_pages/zcash_conf_guide.html) documentation) for authentication.
`rpcuser` and `rpcpassword` in `.env` are only used by zcashd_exporter, but they also must be the same values as in `$ZCASHD_DATADIR/zcash.conf`
### `lightwalletd/docker/zcash.conf` -- read by lightwalletd
The other `zcashd.conf` -- the one read by lightwalletd -- needs to have `rpcbind` (the address of the zcashd it will connect to) set to `zcashd` -- docker-compose networking will make it resolve to the right IP address. Also, it needs to have the same `rpcuser` and `rpcpassword` values that are listed in `$ZCASHD_DATADIR/zcash.conf` to be able to authenticate.

When you edit these lines in `docker-compose.yml`, stopping/starting the individual `lightwalletd` container doesn't actually make the changes happen -- you have to stop/start the whole `docker-compose` ensemble of containers because the ports/network config stuff lives at that level and doesn't seem to be affected by individual container stop/starts. Also if you want to expose `lightwalletd` to the whole internet, you don't need to specify an IP address, `0.0.0.0` works as it should.
