nisplusLDAPobjectDN Attribute

For each mapped NIS+ object, nisplusLDAPobjectDN establishes the location in the LDAP DIT where the object data resides. It also allows specification of the action to take when an LDAP entry is deleted. Each nisplusLDAPobjectDN value has three parts. The first specifies where LDAP data is read from, the second to where it is written, and the third what should happen when LDAP data is deleted. Refer to the following example.

nisplusLDAPobjectDN	rpc_table:\

The above example shows that the rpc.org_dir table object should be read from the DN cn=rpc,ou=nisPlus, (since the value ends in a comma, the value of the defaultSearchBase attribute is appended), with scope base, and that entries with a value of nisplusObjectContainer for the ObjectClass attribute are selected.

The table object is written to the same place. The delete specification is missing, which implies the default action, which is as follows. If the NIS+ table object is deleted, the entire LDAP entry should also be deleted.

If data should be read from, but not written to LDAP, omit the write portion (and the colon separating it from the read part).

nisplusLDAPobjectDN	rpc_table:\

Note that the nisplusObjectContainer object class is not part of RFC 2307. In order to use it, you must configure your LDAP server as detailed in Mapping NIS+ Objects Other Than Table Entries.

For the rpc.org_dir table entries, you could use the following example.

nisplusLDAPobjectDN rpc:ou=Rpc,?one?objectClass=oncRpc:\

The above shows that the table entries are read from and written to the base ou=Rpc. Again, the trailing comma appends the defaultSearchBase value. Select entries that have an objectClass attribute value of oncRpc. When creating an entry in the ou=Rpc container in LDAP, you also must specify top as an objectClass value.

As an example showing a non-default delete specification, consider the following.

nisplusLDAPobjectDN	user_attr:\

The user_attr.org_dir data resides in the ou=People LDAP container, which it shares with account information from other sources, such as the passwd.org_dir NIS+ table.

Select entries in that container that have the solarisAttrKeyValue attribute, since only those contain user_attr.org_dir data. The dbid=user_attr_del portion of the nisplusLDAPobjectDN shows that when an entry in the user_attr.org_dir NIS+ table entry is deleted, deletion of the corresponding LDAP entry (if any) should follow the rules in the rule set identified by the user_attr_del database ID. See nisplusLDAPcolumnFromAttribute Attribute for more information.
