You can configure the API Manager instances to store access tokens in different tables according to their user store domains. This is referred to as user token partitioning and it ensures better security when there are multiple user stores configured in the system. To configure user stores other than the default one, see
The following topics explain how to enable user token partitioning:
You use assertions to embed parameters into tokens and generate a strong access token. You can also use these parameters later for other processing. At the moment, the API Manager only supports UserName as an assertion.
By default, assertions are set to
false in the
<APIM_HOME>/repository/conf/identity/identity.xml. To enable it, set the
<UserName> element to
true. You can add a user name to an access token when generating the key, and verify it by encoding the retrieved access token with Base64.
Storing keys in different tables
<UserName>assertion is enabled, set the
true. It determines whether you want to store the keys in different tables or not.
Set the user store domain names and mappings to new table names. For example,
- if userId = foo.com/admin where 'foo.com' is the user store domain name, then a 'mapping:domain' combo can be defined as 'A:foo.com'
- 'A' is the mapping for the table that stores tokens relevant to users coming from the 'foo.com' user store
In this case, the actual table name is
IDN_OAUTH2_ACCESS_TOKEN_A. We use a mapping simply to prevent any issues caused by lengthy table names when lengthy domain names are used. You must manually create the tables you are going to use to store the access tokens in each user store (i.e., manually create the tables
IDN_OAUTH2_ACCESS_TOKEN_Baccording to the following defined domain mapping). This table structure is similar to the
IDN_OAUTH2_ACCESS_TOKENtable defined in the api-manager dbscript, which is inside the
You can provide multiple mappings separated by commas as follows. Note that the domain names need to be specified in upper case.
According to the information given above, change the
<OAuth>element in the
<APIM_HOME>/repository/conf/identity/identity.xmlfile as shown in the following example:
