> Support text file for user authentication instead of using PAM
> --------------------------------------------------------------
>
> Key: DRILL-7573
> URL: https://issues.apache.org/jira/browse/DRILL-7573
> Project: Apache Drill
> Issue Type: Improvement
> Components: Server, Web Server
> Affects Versions: 1.17.0
> Reporter: Dobes Vandermeer
> Priority: Major
>
> Currently plain login using PAM as its user database. However, in a
> containerized or server environment the passwd file is generally kept static,
> so some other mechanism for managing users is preferred. Also, pam does not
> by default come with an easy to way to check passwords other than via the
> passwd/shadow files.
> It would be great if there was another authentication method included in
> drill that was easier to use in a containerized environment.
> Reading the usernames and password from a specific file would probably be the
> simplest mechanism.
