       slurpd - Standalone LDAP Update Replication Daemon

       /usr/libexec/slurpd   [-d   debug-level]	  [-f  slapd-config-file]  [-r
       slapd-replog-file] [-t temp-dir] [-o] [-k srvtab-file]

       Slurpd is used to propagate changes from one slapd database to another.
       If  slapd is configured to produce a replication log, slurpd reads that
       replication log and sends the changes to the slave slapd instances  via
       the  LDAP  protocol.  slurpd is typically invoked at boot time, usually
       out of /etc/rc.local.

       Upon startup, slurpd normally forks and disassociates itself  from  the
       invoking	 tty,  then  reads  the	 replication  log (given either by the
       replogfile directive in the slapd config file, or by  the  -r  command-
       line  option).  If the replication log file does not exist or is empty,
       slurpd goes to sleep.  It periodically wakes up and checks  to  see  if
       there are any changes to be propoagated.

       When  slurpd notices that there are changes to propagate to slave slapd
       instances, it locks the replication log, makes its  own	private	 copy,
       releases	 the lock, and forks one copy of itself for each replica slapd
       to be updated.  Each child process binds to the slave slapd as  the  DN
       given by the binddn option to the replica directive in the slapd config
       file, and sends the changes.

       See slapd(8) for details on the standalone LDAP daemon.

       Note that slurpd reads replication directive  from  slapd.conf(5),  but
       uses  ldap.conf(5)  to obtain other configuration settings (such as TLS

       -d debug-level
	      Turn on debugging as defined by debug-level.  If this option  is
	      specified,  even	with  a zero argument, slurpd will not fork or
	      disassociate from the invoking terminal.	Some general operation
	      and  status  messages  are printed for any value of debug-level.
	      debug-level is taken as a bit string, with each bit  correspond‐
	      ing  to a different kind of debugging information.  See <ldap.h>
	      for details.

       -f slapd-config-file
	      Specifies	 the  slapd  configuration  file.   The	  default   is

       -r slapd-replog-file
	      Specifies	 the name of the slapd replication logfile.  Normally,
	      the name of the replication log file is read from the slapd con‐
	      figuration file.	The file should be located in a directory with
	      limited read/write/execute access.  The -r option allows you  to
	      override	this.	In  conjunction	 with  the  -o option, you can
	      process a replication log file in a "one-shot" mode.  For	 exam‐
	      ple,  if	slurpd has encountered errors in processing a replica‐
	      tion log, you can run it in one-shot mode and give the rejection
	      file name as the argument to the -r option, once you've resolved
	      the problem which caused the replication to fail.

       -o     Run in "one-shot" mode.  Normally, slurpd processes  the	replog
	      file  and	 then  watches	for  more  replication	entries	 to be
	      appended.	 In one-shot mode, slurpd processes a replication  log
	      and exits.

       -t temp-dir
	      slurpd  copies the replication log to a working directory before
	      processing  it.	The   directory	  permissions	should	 limit
	      read/write/execute  access as temporary files may contain sensi‐
	      tive information.	 This option allows you to specify  the	 loca‐
	      tion  of	these  temporary files.	 The default is /var/db/openl‐

       -k srvtab-file
	      Specify the location of the kerberos srvtab file which  contains
	      keys  for	 the  replica  slapd  instances.  Overrides the srvtab
	      argument to the replica directive	 in  the  slapd	 configuration

       To  start  slurpd  and  have  it	 fork and detach from the terminal and
       process the replication logs generated by slapd, just type:


       To start slurpd with an alternate slapd configuration file, and turn on
       voluminous debugging which will be printed on standard error, type:

	    /usr/libexec/slurpd -f /etc/openldap/slapd.conf -d 255

       ldap(3), ldap.conf(5), slapd.conf(5), slapd.replog(5), slapd(8)
