Sudoers doesn't work with User_Alias as expected.

Solution Verified - Updated -

Issue

  • There is an user realuser and the alias for the same is USER_ALIAS_NEW.
  • The relevant part of file /etc/sudoers is as follows:
User_Alias  USER_ALIAS_NEW=realuser
root                ALL=(ALL)        ALL
Cmnd_Alias USER_CMDS =  cp /tmp/sc-USER_ALIAS_NEW/new.pem /etc/somelocation/;
USER_ALIAS_NEW ALL = (root) NOPASSWD: USER_CMDS
  • The command cp needs to run as root by user realuser.
  • The actual command it needs to run is cp /tmp/sc-realuser/new.pem /etc/somelocation/

Environment

  • Red Hat Enterprise Linux (RHEL) 5, 6
  • sudoers
