Numeric names are no longer supported in RHEL 7.x

Solution Verified - Updated -

Issue

  • As of the release of shadow-utils-4.1.5.1-25.el7, all numeric values are not supported. This creates issues with existing workflow, where clients have been allocated numeric usernames for SSH/SFTP/FTP services.
  • We'd like to know if there's a way to create a user with only numeric characters in RHEL 7.7?

Environment

  • Red Hat Enterprise Linux (RHEL) 7.x
