Searching subordinate user IDs causes errant matches. This has been fixed upstream, and is included in passwd-4.8 and the issue does not appear to exist in groovy. https://github.com/shadow- maint/shadow/commit/fd4405b763d26649339069532e79bd45013c8c38 I believe this fix should be backported to xenial and bionic.
