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.
