slapd.replog(5)
NAME
slapd.replog - slapd replication log format
SYNOPSIS
slapd.replog slapd.replog.lock
DESCRIPTION
The file slapd.replog is produced by the stand-alone LDAP
daemon, slapd(8), when changes are made to its local
database that are to be propagated to one or more replica
slapds. The file consists of zero or more records, each
one corresponding to a change, addition, or deletion from
the slapd database. The file is meant to be read and pro
cessed by slurpd(8), the stand-alone LDAP update replica
tion daemon. The records are separated by a blank line.
Each record has the following format.
- The record begins with one or more lines indicating the
replicas to which the change is to be propagated: - replica: <hostname[:portnumber]>
- Next, the time the change took place given, as the number
of seconds since 00:00:00 GMT, Jan. 1, 1970, with an
optional decimal extension, in order to make times unique.
Note that slapd does not make times unique, but slurpd
makes all times unique in its copies of the replog files.
time: <integer[.integer]>- Next, the distinguished name of the entry being changed is
given:
dn: <distinguishedname>- Next, the type of change being made is given:
changetype: <[modify|add|delete|modrdn]>- Finally, the change information itself is given, the for
mat of which depends on what kind of change was specified
above. For a changetype of modify, the format is one or more of the following:
add: <attributetype>
<attributetype>: <value1>
<attributetype>: <value2>
...
- Or, for a replace modification:
replace: <attributetype>
<attributetype>: <value1>
<attributetype>: <value2>
...
- Or, for a delete modification:
delete: <attributetype>
<attributetype>: <value1>
<attributetype>: <value2>
...
- If no attributetype lines are given, the entire attribute is to be deleted.
- For a changetype of add, the format is:
<attributetype1>: <value1>
<attributetype1>: <value2>
...
<attributetypeN>: <value1>
<attributetypeN>: <value2>- For a changetype of modrdn, the format is:
newrdn: <newrdn>
deleteoldrdn: 0 | 1- where a value of 1 for deleteoldrdn means to delete the
values forming the old rdn from the entry, and a value of
0 means to leave the values as non-distinguished
attributes in the entry. - For a changetype of delete, no additional information is needed in the record.
- The format of the values is the LDAP Directory Interchange
Format described in ldif(5). - Access to the slapd.replog file is synchronized through
the use of flock(3) on the file slapd.replog.lock. Any
process reading or writing this file should obey this
locking convention.

tion on one of each type of change.
