You can export security data from one security realm or security provider and import the data into another realm or provider. The following sections provide information about exporting and importing security data.
WebLogic security realms persist different kinds of security data — for example, users and groups (for the WebLogic Authentication provider), security policies (for the XACML Authorization provider), security roles (for the XACML Role Mapping provider), and credential maps (for the WebLogic Credential Mapping provider). When you configure a new security realm or a new security provider, you may prefer to use the security data from your existing realm or provider, rather than recreate all the users, groups, policies, roles, and credential maps. Several WebLogic security providers support security data migration. This means you can export security data from one security realm, and import it into a new security realm. You can migrate security data for each security provider individually, or migrate security data for all the WebLogic security providers at once (that is, security data for an entire security realm). Note that you can only migrate security data from one provider to another if the providers use the same data format. See Formats and Constraints Supported by WebLogic Security Providers. You migrate security data through the WebLogic Administration Console or by using the WebLogic Scripting Tool (WLST).
Migrating security data may be helpful when you:
Transition from development to production mode.
Copy production mode security configurations to security realms in new WebLogic domains.
Move data from one security realm to a new security realm in the same WebLogic domain, where one or more of the default WebLogic security providers will be replaced with new security providers.
The remainder of this section describes security migration concepts, the formats and constraints supported by the WebLogic security providers, and steps for migrating security data with WLST.
To migrate security data with the WebLogic Administration Console, see the following topics in the Oracle WebLogic Server Administration Console Help:
A format is a data format that specifies how security data should be exported or imported. Supported formats are the list of data formats that a given security provider understands how to process.
Constraints are key/value pairs that specify options to the export or import process. Use constraints to control which security data is exported to or imported from the security provider's database (in the case of the WebLogic Server security providers, the embedded LDAP server). For example, you may want to export only users (not groups) from an Authentication provider's database. Supported constraints are the list of constraints you can specify during the migration process for a particular security provider. For example, you can specify that an Authentication provider's database be used to import users and groups, but not security policies.
Export files are the files to which security data is written (in the specified format) during the export portion of the migration process. Import files are files from which security data is read (also in the specified format) during the import portion of the migration process. Both export and import files are simply temporary storage locations for security data as it is migrated from one security provider's data store to another security provider's data store.
In order for security data to be exported and imported between security providers, both security providers must process the same format. Some data formats used for the WebLogic Server security providers are unpublished; therefore, you cannot currently migrate security data from a WebLogic security provider to a custom security provider, or vice versa, using the unpublished formats.
WebLogic security providers support the following import and export formats.
Table 8-1 Import and Export Formats Supported by the WebLogic Security Providers
WebLogic security providers support the following import and export constraints.
Table 8-2 Constraints Supported by the WebLogic Security Providers
WebLogic Security Provider | Supported Constraints | Description |
---|---|---|
Default Authentication |
users groups |
Export all users or all groups |
|
none |
N/A |
WebLogic Credential Mapping |
passwords |
With the constraint passwords=cleartext, passwords will be exported in clear text. Otherwise, they will be exported in encrypted form. |
|
partners |
Which partners to import or export. The constraint value can be one of:
|
|
certificates |
Which certificates to import or export. The constraint value can be one of the following:
|
|
passwords |
With the constraint passwords=cleartext, passwords will be exported in clear text. Otherwise, they will be exported in encrypted form. |
|
importMode |
Specifies how to resolve name conflicts between the imported data and existing data in the SAML registry. The constraint value can be one of the following:
|
When exporting from the WebLogic Credential Mapping provider, SAML Credential Mapping provider, or SAML Identity Asserter, you need to specify whether or not the passwords for the credentials are exported in clear text. The constraint passwords=cleartext
specifies that passwords will be exported in clear text. Otherwise, they will be exported in encrypted form. The mechanism used to encrypt passwords in each WebLogic domain is different; therefore, you want to export passwords in clear text if you plan to use them in a different WebLogic domain. After the credential maps are imported into the new WebLogic domain, the passwords are encrypted. Carefully protect the directory and file in which you export credential maps in clear text as secure data is available on your system during the migration process.
Note:
By default, the WebLogic Authentication provider stores passwords using a one-way hash. Passwords that have been encrypted by this provider cannot be unencrypted when you export data even if you use thepasswords=cleartext
constraint. If you want to be able to export passwords in clear text from this provider, you must set the Enable Password Digests attribute to true
prior to creating or updating those passwords. For more information, see "Default Authentication Provider: Provider Specific" in Oracle WebLogic Server Administration Console Help.You can use the WebLogic Scripting Tool (WLST) to export and import data from a security provider. Access the Runtime MBean for the security provider and use its importData
or exportData
operation. For example, you might use WLST to import data using commands like these:
domainRuntime() cd('DomainServices/DomainRuntimeService/DomainConfiguration/mydomain /SecurityConfiguration/mydomain/DefaultRealm/myrealm/path-to-MBean/mbeanname') cmo.importData(format,filename,constraints)
where:
mbeanname
—Name of the security provider MBean.
format
—A format that is valid for the particular security provider. See Table 8-1.
filename
—The directory location and filename in which to export or import the security data. Remember that, regardless of whether you are using a UNIX or Windows operating system, you need to use a forward slash, not a back slash, as a path separator for pathname arguments in WLST commands.
constraints
—The constraints that limit the data to be exported or imported
