NAME
/etc/adduser.conf - configuration file for adduser(8) and addgroup(8).
DESCRIPTION
The file /etc/adduser.conf contains defaults for the programs adduser(8) , addgroup(8) ,
deluser(8) and delgroup(8). Each line holds a single value pair in the form option =
value. Double or single quotes are allowed around the value, as is whitespace around the
equals sign. Comment lines must have a hash sign (#) in the first column.
The valid configuration options are:
DSHELL The login shell to be used for all new users. Defaults to /bin/bash.
DHOME The directory in which new home directories should be created. Defaults to /home.
GROUPHOMES
If this is set to yes, the home directories will be created as /home/[group-
name]/user. Defaults to no.
LETTERHOMES
If this is set to yes, then the home directories created will have an extra direc-
tory inserted which is the first letter of the loginname. For example:
/home/u/user. Defaults to no.
SKEL The directory from which skeletal user configuration files should be copied.
Defaults to /etc/skel.
FIRST_SYSTEM_UID and LAST_SYSTEM_UID
specify an inclusive range of UIDs from which system UIDs can be dynamically allo-
cated. Default to 100 - 999. Please note that system software, such as the users
allocated by the base-passwd package, may assume that UIDs less than 100 are unal-
located.
FIRST_UID and LAST_UID
specify an inclusive range of UIDs from which normal user's UIDs can be dynamically
allocated. Default to 1000 - 29999.
FIRST_SYSTEM_GID and LAST_SYSTEM_GID
specify an inclusive range of GIDs from which system GIDs can be dynamically allo-
cated. Default to 100 - 999.
FIRST_GID and LAST_GID
specify an inclusive range of GIDs from which normal group's GIDs can be dynami-
cally allocated. Default to 1000 - 29999.
USERGROUPS
If this is set to yes, then each created user will be given their own group to use.
If this is no, then each created user will be placed in the group whose GID is
USERS_GID (see below). The default is yes.
USERS_GID
If USERGROUPS is no, then USERS_GID is the GID given to all newly-created users.
The default value is 100.
DIR_MODE
If set to a valid value (e.g. 0755 or 755), directories created will have the spec-
ified permissions as umask. Otherwise 0755 is used as default.
SETGID_HOME
If this is set to yes, then home directories for users with their own group ( USER-
GROUPS=yes ) will have the setgid bit set. This was the default setting for adduser
versions << 3.13. Unfortunately it has some bad side effects, so we no longer do
this per default. If you want it nevertheless you can still activate it here.
QUOTAUSER
If set to a nonempty value, new users will have quotas copied from that user. The
default is empty.
NAME_REGEX
User and group names are checked against this regular expression. If the name
doesn't match this regexp, user and group creation in adduser is refused unless
--force-badname is set. With --force-badname set, only weak checks are performed.
The default is the most conservative ^[a-z][-a-z0-9]*$.
SKEL_IGNORE_REGEX
Files in /etc/skel/ are checked against this regex, and not copied to the newly
created home directory if they match. This is by default set to the regular
expression matching files left over from unmerged config files
(dpkg-(old|new|dist)).
ADD_EXTRA_GROUPS
Setting this to something other than 0 (the default) will cause adduser to add
newly created non-system users to the list of groups defined by EXTRA_GROUPS
(below).
EXTRA_GROUPS
This is the list of groups that new non-system users will be added to. By default,
this list is 'dialout cdrom floppy audio video plugdev users games'
NOTES
VALID NAMES
adduser and addgroup enforce conformity to IEEE Std 1003.1-2001, which allows only
the following characters to appear in group and user names: letters, digits, under-
scores, periods, at signs (@) and dashes. The name may no start with a dash. The
"$" sign is allowed at the end of usernames (to conform to samba).
An additional check can be adjusted via the configuration parameter NAME_REGEX to
enforce a local policy.
