Top Forums UNIX for Advanced & Expert Users Permissions on a directory in /home for all users Post 302921852 by Don Cragun on Monday 20th of October 2014 02:30:49 PM

And you have now set it up so that no user on your system has any private files; every file that they create in any directory on your system will be readable and writeable by every other user in the same group. Fortunately, I use the Korn shell instead of bash, so this wouldn't affect me.

Before you modified everybody'a .bashrc, did you at least warn them that they need to undo what you did or manually chmod every file that they create in any other directory?

Did you consider just asking users in this group to chmod files they create under this shared directory.

Did you consider writing a set-UID application that would allow users in that group to change the mode of any file under that directory (AND ONLY under that direcotry) to something any user in the group could use (and send a note to the offending file's creator and that person's supervisor) when it was needed?

At any company I've ever worked for, what you did would be a fireable offense. Please reconsider this action.

SSS_USERADD(8)							 SSSD Manual pages						    SSS_USERADD(8)

NAME
sss_useradd - create a new user SYNOPSIS
sss_useradd [options] LOGIN DESCRIPTION
sss_useradd creates a new user account using the values specified on the command line plus the default values from the system. OPTIONS
-u,--uid UID Set the UID of the user to the value of UID. If not given, it is chosen automatically. -c,--gecos COMMENT Any text string describing the user. Often used as the field for the user's full name. -h,--home HOME_DIR The home directory of the user account. The default is to append the LOGIN name to /home and use that as the home directory. The base that is prepended before LOGIN is tunable with "user_defaults/baseDirectory" setting in sssd.conf. -s,--shell SHELL The user's login shell. The default is currently /bin/bash. The default can be changed with "user_defaults/defaultShell" setting in sssd.conf. -G,--groups GROUPS A list of existing groups this user is also a member of. -m,--create-home Create the user's home directory if it does not exist. The files and directories contained in the skeleton directory (which can be defined with the -k option or in the config file) will be copied to the home directory. -M,--no-create-home Do not create the user's home directory. Overrides configuration settings. -k,--skel SKELDIR The skeleton directory, which contains files and directories to be copied in the user's home directory, when the home directory is created by sss_useradd. This option is only valid if the -m (or --create-home) option is specified, or creation of home directories is set to TRUE in the configuration. -Z,--selinux-user SELINUX_USER The SELinux user for the user's login. If not specified, the system default will be used. -h,--help Display help message and exit. THE LOCAL DOMAIN
In order to function correctly, a domain with "id_provider=local" must be created and the SSSD must be running. The administrator might want to use the SSSD local users instead of traditional UNIX users in cases where the group nesting (see sss_groupadd(8)) is needed. The local users are also useful for testing and development of the SSSD without having to deploy a full remote server. The sss_user* and sss_group* tools use a local LDB storage to store users and groups. SEE ALSO
sss_groupadd(8), sss_groupdel(8), sss_groupshow(8), sss_groupmod(8), sss_userdel(8), sss_usermod(8). AUTHORS
