наложение ссылочной целостности на slapd (Referential Integrity overlay to slapd)
Имя (Name)
slapo-refint - Referential Integrity overlay to slapd
Синопсис (Synopsis)
ETCDIR/slapd.conf
Описание (Description)
The Referential Integrity overlay can be used with a backend
database such as slapd-mdb(5) to maintain the cohesiveness of a
schema which utilizes reference attributes.
Integrity is maintained by updating database records which
contain the named attributes to match the results of a modrdn or
delete operation. For example, if the integrity attribute were
configured as manager, deletion of the record
"uid=robert,ou=people,dc=example,dc=com" would trigger a search
for all other records which have a manager attribute containing
that DN. Entries matching that search would have their manager
attribute removed. Or, renaming the same record into
"uid=george,ou=people,dc=example,dc=com" would trigger a search
for all other records which have a manager attribute containing
that DN. Entries matching that search would have their manager
attribute deleted and replaced by the new DN.
rootdn must be set for the database. refint runs as the rootdn
to gain access to make its updates. rootpw is not needed.
Конфигурация (Configuration)
These slapd.conf options apply to the Referential Integrity
overlay. They should appear after the overlay directive.
refint_attributes <attribute> [...]
Specify one or more attributes for which integrity will be
maintained as described above.
refint_nothing <string>
Specify an arbitrary value to be used as a placeholder
when the last value would otherwise be deleted from an
attribute. This can be useful in cases where the schema
requires the existence of an attribute for which
referential integrity is enforced. The attempted deletion
of a required attribute will otherwise result in an Object
Class Violation, causing the request to fail. The string
must be a valid DN.
refint_modifiersname <DN>
Specify the DN to be used as the modifiersName of the
internal modifications performed by the overlay. It
defaults to "cn=Referential Integrity Overlay".
Modifications performed by this overlay are not propagated during
replication. This overlay must be configured identically on
replication consumers in order to maintain full synchronization
with the provider.
