Unable to connect to AD4D (Astra DB for DSE)

[ims-swilkinson]

Using the Docker image (datastax/cql-proxy:v0.1.4 or datastax/cql-proxy:v0.1.3) I'm unable to connect to my AD4D (Astra DB for DSE) cluster.

• The cluster is an "Astra DSE Edition Workload" on the E60 tier (48 vCPU, 366 DRAM, 2TB STORAGE).
• I can connect to it using cqlsh.

I initially tried using a client token:

docker run -a STDIN -a STDOUT -a STDERR -p 9042:9042 datastax/cql-proxy:v0.1.4 \
    --astra-token $AD4D_CLIENT_TOKEN \
    --astra-database-id $ASTRA_DB_ID

But I got this error:

cql-proxy: error: unable to connect to cluster unknown authenticator: org.apache.cassandra.auth.AstraAuthenticator

I then tried building an image which with the above image as the base, copying in the secure connect bundle, and used username, password and SCB path parameters:

docker run -a STDIN -a STDOUT -a STDERR -p 9042:9042 5c65463aed00 \
    --username $AD4D_CLIENT_ID \
    --password $AD4D_CLIENT_SECRET \
    --astra-database-id $ASTRA_DB_ID \
    -b "/scb.zip"

But I got the exact same error.

Adding the --debug parameter didn't yield any extra info.
I know this may be an AD4D issue, and I have reported it to our support contact at DataStax.

Someone more competent in Go than myself tells me this change to the source code will fix it:

In cql-proxy-main/proxycore/auth.go, in the func (d *passwordAuth) InitialResponse(authenticator string) ([]byte, error) function, add this case:

        case "org.apache.cassandra.auth.AstraAuthenticator":
                return d.makeToken(), nil
