slurpd - Standalone LDAP Update Replication Daemon
/usr/lib/ultrapossum/slapd/libexec/slurpd [-d debug-level] [-f
slapd-config-file] [-r slapd-replog-file] [-t temp-dir] [-o] [-k
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

specified, even with a zero argument, slurpd will not fork or

debug-level is taken as a bit string, with each bit

Specifies the name of the slapd replication logfile. Normally,
the name of the replication log file is read from the slapd
configuration 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
example, if slurpd has encountered errors in processing a
replication 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

appended. In one-shot mode, slurpd processes a replication log
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
sensitive information. This option allows you to specify the
location of these temporary files. The default is

process the replication logs generated by slapd, just type:
