What is your solution for credentials access on RStudio Server?

I love the keyring package, however it's been suggested that it currently doesn't play well with RStudio Server.

Community hive mind, what do you use to store/access things like database credentials outside of your mainline code?

I've come across the config package. Are there any alternatives? Or is there plan for keyring support soon?

Our two big sources are Oracle and Hadoop. We're using Oracle Wallet for Oracle and keytabs for Hadoop. So both of our solutions are outside R.
