Sudo does not read files in /etc/sudoers.d/* which is containing "dot" character in filename

Solution Verified - Updated -

Issue

  1. Sudo drop-in file is created for user bob.smith allowing the user to run any command without password.

    # cat /etc/sudoers.d/bob.smith 
bob.smith  ALL=(ALL)       NOPASSWD: ALL

  2. However, the sudo rule is not listed:

    # sudo -ll -U bob.smith
User bob.smith is not allowed to run sudo on hostA.

  3. Sudo would print the rule if the line is copied into /etc/sudoers.

  4. Sudo ignores file names with "dot" character.
