Arvados

On Centos7 arvados-login-sync fails to manage the users correctly because the commands used to manage the user (adduser, deluser) either do not exist or take different parameters formats:

• When managing groups:
  • adduser is used in the script to add the user to groups, with the syntax:
    

            system("adduser", username, addgroup)
    

    
    which translates to
    

    adduser username addgroup
    

    
    This format is invalid in Centos, and results on the script returning the help page for each command
  • deluser is used to remove the user from groups. This command does not exist in Centos.
    

            system("deluser", username, removegroup)
    

    
    returns with an error.
