-.B searchbase, scope, filter, attrs, attrsonly, sizelimit,
+.BR searchbase ", " scope ", " filter ", " attrs ", " attrsonly ", " sizelimit ", "
and
.B timelimit
parameters as in the normal search specification.
The \fBscope\fP defaults to \fBsub\fP, the \fBfilter\fP defaults to
-\fB(objectclass=*)\fP, and there is no default \fBsearchbase\fP. The
+\fB(objectclass=*)\fP, while there is no default \fBsearchbase\fP. The
\fBattrs\fP list defaults to \fB"*,+"\fP to return all user and operational
attributes, and \fBattrsonly\fP is unset by default.
The \fBsizelimit\fP and \fBtimelimit\fP only
accept "unlimited" and positive integers, and both default to "unlimited".
+The \fBsizelimit\fP and \fBtimelimit\fP parameters define
+a consumer requested limitation on the number of entries that can be returned
+by the LDAP Content Synchronization operation; as such, it is intended
+to implement partial replication based on the size of the replicated database
+and on the time required by the synchronization.
Note, however, that any provider-side limits for the replication identity
will be enforced by the provider regardless of the limits requested
by the LDAP Content Synchronization operation, much like for any other
for the first 10 times and then retry every 300 seconds for the next 3
times before stop retrying. The `+' in <# of retries> means indefinite
number of retries until success.
+If no
+.B retry
+was specified, by default syncrepl retries every hour forever.
The schema checking can be enforced at the LDAP Sync
consumer site by turning on the
.B schemachecking
-parameter. The default is off.
+parameter. The default is \fBoff\fP.
+Schema checking \fBon\fP means that replicated entries must have
+a structural objectClass, must obey to objectClass requirements
+in terms of required/allowed attributes, and that naming attributes
+and distinguished values must be present.
+As a consequence, schema checking should be \fBoff\fP when partial
+replication is used.
+
+The
+.B network\-timeout
+parameter sets how long the consumer will wait to establish a
+network connection to the provider. Once a connection is
+established, the
+.B timeout
+parameter determines how long the consumer will wait for the initial
+Bind request to complete. The defaults for these parameters come
+from
+.BR ldap.conf (5).
A
.B bindmethod
.B authzid
parameter may be used to specify an authorization identity.
Specific security properties (as with the
-.B sasl-secprops
+.B sasl\-secprops
keyword above) for a SASL bind can be set with the
.B secprops
option. A non default SASL realm can be set with the
.B realm
option.
+The identity used for synchronization by the consumer should be allowed
+to receive an unlimited number of entries in response to a search request.
The provider, other than allow authentication of the syncrepl identity,
should grant that identity appropriate access privileges to the data
that is being replicated (\fBaccess\fP directive), and appropriate time
-and size limits (\fBlimits\fP directive).
+and size limits.
+This can be accomplished by either allowing unlimited \fBsizelimit\fP
+and \fBtimelimit\fP, or by setting an appropriate \fBlimits\fP statement
+in the consumer's configuration (see \fBsizelimit\fP and \fBlimits\fP
+for details).
+The
+.B keepalive
+parameter sets the values of \fIidle\fP, \fIprobes\fP, and \fIinterval\fP
+used to check whether a socket is alive;
+.I idle
+is the number of seconds a connection needs to remain idle before TCP
+starts sending keepalive probes;
+.I probes
+is the maximum number of keepalive probes TCP should send before dropping
+the connection;
+.I interval
+is interval in seconds between individual keepalive probes.
+Only some systems support the customization of these values;
+the
+.B keepalive
+parameter is ignored otherwise, and system-wide settings are used.
The
.B starttls
tls_reqcert setting defaults to "demand" and the other TLS settings
default to the same as the main slapd TLS settings.
+The
+.B suffixmassage
+parameter allows the consumer to pull entries from a remote directory
+whose DN suffix differs from the local directory. The portion of the
+remote entries' DNs that matches the \fIsearchbase\fP will be replaced
+with the suffixmassage DN.
+
Rather than replicating whole entries, the consumer can query logs of
data modifications. This mode of operation is referred to as \fIdelta
syncrepl\fP. In addition to the above parameters, the
parameters must be set appropriately for the log that will be used. The
.B syncdata
parameter must be set to either "accesslog" if the log conforms to the
-.BR slapo-accesslog (5)
+.BR slapo\-accesslog (5)
log format, or "changelog" if the log conforms
to the obsolete \fIchangelog\fP format. If the
