LDAP_DIRECTORY_ACCESS

Property Description

Parameter type

String

Syntax

LDAP_DIRECTORY_ACCESS = { NONE | PASSWORD | SSL }

Default value

NONE

Modifiable

ALTER SYSTEM

Basic

No

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

Since there is only one LDAP_DIRECTORY_ACCESS initialization parameter per CDB, all the PDBs in a CDB will use the Oracle Internet Directory authentication specified by the parameter.

For a CDB, 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 will 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 the 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 since there is only one sqlnet.ora file for a CDB, the wallet location in sqlnet.ora is not supported for CDBs, because each PDB must have its own wallet.

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.

For non-CDBs, 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)
