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 line.

       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/[groupname]/user.  Defaults to no.

       LETTERHOMES
              If  this  is  set to yes, then the home directories created will
              have an extra directory 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 allocated. Default to 100 - 999.

       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.

       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 specified permissions. Otherwise 0755 is used as
              default.

       SETGID_HOME
              If this is set to yes, then  home  directories  for  users  with
              their own group ( USERGROUPS=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 names are checked against this regular expression.  If  the
              name  doesn’t match this regexp, user creation 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]*$.
