SYNC-ACCOUNTS-CREATEUSER(8)					 chiark utilities				       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 data-
       bases.

       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 remotefor-
       mat 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_CRE-
       ATE_* variables are set, or have sensible values.
