      Description

      In a typical configuration, group name is obtained from AD through SSSD/LDAP. AD permits group names with space (e.g. "Domain Users").
      Unfortunately, the present implementation of ShellBasedUnixGroupMapping parses the output of shell command "id -Gn", and assumes group names are separated by space.
      This could be achieved by using a combination of shell scripts, for example,
      bash -c 'id -G weichiu | tr " " "\n" | xargs -I % getent group "%" | cut -d":" -f1'
      But I am still looking for a more compact form, and potentially more efficient one.
