1.161 LDAP_DIRECTORY_ACCESS

LDAP_DIRECTORY_ACCESS specifies whether Oracle refers to Oracle Internet Directory for user authentication information.

Property Description

Parameter type

String

Syntax

LDAP_DIRECTORY_ACCESS = { NONE | PASSWORD | SSL }

Default value

NONE

Modifiable

ALTER SYSTEM

Modifiable in a PDB

Yes

Basic

No

If directory access is turned on, then this parameter also specifies how users are authenticated.

Values

  • NONE

    Oracle does not refer to Oracle Internet Directory for Enterprise User Security information.

  • PASSWORD

    Oracle tries to connect to the enterprise directory service using the database password stored in the database wallet. If that fails, then the Oracle Internet Directory connection fails and the database will not be able to retrieve enterprise roles and schema mappings upon enterprise user login.

  • SSL

    Oracle tries to connect to Oracle Internet Directory using SSL.

Using LDAP_DIRECTORY_ACCESS with PDBs

PDBs can use password and SSL authentication with Oracle Internet Directory when the default database wallet location is used.

The LDAP_DIRECTORY_ACCESS initialization parameter is PDB-specific. If you set this parameter in a CDB root container, then all PDBs in the CDB will use that setting of the parameter. If you set this parameter in a PDB, then the parameter setting affects only that PDB. You can use ALTER SYSTEM to set this parameter in a PDB.

For a CDB, if the wallet location is not specified in sqlnet.ora, then the default database wallet path is:

ORACLE_BASE/admin/db-unique-name/pdb-GUID/wallet (if ORACLE_BASE is set)

or:

ORACLE_HOME/admin/db-unique-name/pdb-GUID/wallet (if ORACLE_BASE is not set)

The exception is for the root database, which has a default wallet path of:

ORACLE_BASE/admin/db-unique-name/wallet (if ORACLE_BASE is set)

or:

ORACLE_HOME/admin/db-unique-name/wallet (if ORACLE_BASE is not set)

All PDBs in a CDB have the same database unique name. By placing wallets in the default location, each PDB can have its own identity.

Note that because there is only one sqlnet.ora file for a CDB, the wallet location in sqlnet.ora is only used by the CDB root container. Because each PDB must have its own wallet, a PDB wallet will be specified by the pdb-GUID under the wallet location in sqlnet.ora.

For the root container of a CDB, the wallet location is:

WALLET_LOCATION_specified_in_sqlnet.ora

For each PDB of the CDB, the wallet location is:

WALLET_LOCATION_specified_in_sqlnet.ora/pdb-GUID/

Note:

Oracle databases are registered with Oracle Internet Directory using Database Configuration Assistant (DBCA). For registration with Oracle Internet Directory to work, all the PDBs for a CDB must be registered using DBCA.

Using LDAP_DIRECTORY_ACCESS with Non-CDBs

For non-CDBs, if the wallet location is not specified in sqlnet.ora, then the default database wallet path is:

ORACLE_BASE/admin/db-unique-name/wallet (if ORACLE_BASE is set)

or:

ORACLE_HOME/admin/db-unique-name/wallet (if ORACLE_BASE is not set)
