sync-accounts-createuser(8)


NAME

   sync-accounts-createuser - helper/hook program for sync-accounts

SYNOPSIS

   SYNCUSER_CREATE_var=value... sync-accounts-createuser

DESCRIPTION

   sync-accounts-createuser is invoked by sync-accounts when sync-accounts
   is creating a local account.

   It must perform all of the tasks involved with local  account  creation
   except  for  the  actual  changes  to  the  password,  shadow and group
   databases.

   At the very minimum, it must create the new  account's  home  directory
   (with  appropriate permissions).  The supplied sync-accounts-createuser
   script does exactly that.

   It may also suggest to sync-accounts modifications to the new account's
   passwd entry.

INVOCATION

   When  sync-accounts-createuser is invoked, the passwd and group entries
   will not yet have been set up, so it  may  not  rely  on  them.   sync-
   accounts-createuser  will not be supplied with any arguments.  However,
   the following environment variables will be set, giving  details  about
   the account to be created:
     SYNCUSER_CREATE_USER
     SYNCUSER_CREATE_UID
     SYNCUSER_CREATE_GID
     SYNCUSER_CREATE_COMMENT
     SYNCUSER_CREATE_HOME
     SYNCUSER_CREATE_SHELL

RESULTS

   sync-accounts-createuser should usually produce no output.

   It can inhibit the creation of the user by outputting a single line not
   containing a colon; in this case, a diagnostic message will be  written
   to sync-accounts's logfile, and the user will be skipped.

   Alternatively,  it may write out an alternative password file entry, in
   which case sync-accounts will use  the  supplied  data  for  the  local
   passwd  file  instead of that from the remote host.  The line should be
   in Sys-V passwd file format (regardless of localformat or  remoteformat
   settings).     The    username    field    should    be    taken   from
   SYNCUSER_CREATE_USER, and the password field should be x.

EXIT STATUS

   0      All went well, or we wrote a line without a colon  to  say  that
          the account should not be created.

   any other
          There  were  serious  problems and sync-accounts should bomb out
          immediately.

FILES

   None.

ENVIRONMENT

   See above.

BUGS

   The supplied sync-accounts-createuser does not check that  it  was  not
   supplied   with   any   arguments;   nor   does   it   check  that  the
   SYNCUSER_CREATE_* variables are set, or have sensible values.
