http://download.oracle.com/javase/6/docs/technotes/guides/security/jaas/JAASLMDevGuide.htmlThis describes how to add Identity Asserter into Weblogic.
This is needed when identity of user is authenticated at external component. User id is provided as token in HTTP header of request.

<!-- The ActiveTypes attribute (a settable attribute inherited from the
weblogic.management.security.authentication.IdentityAsserter mbean)
contains the subset of your mbean's SupportedTypes that are active
in the realm.
Which way you should default the active types attribute depends
on your token types. The basic rule is that for any token
type, there must only be one identity asserter in the realm with
that token type as an active type. In short, you can only have
one identity asserter turned on for a given type.
If your token types are commonly implemented by other identity
asserters (eg. X509 certificates), then you should not set them
as default active types. Otherwise, it would be very easy for
an administrator to configure an invalid realm where more than
one identity asserter has the same type turned on. Best
practice is that all the identity asserters turn off the type
by default then the administrator manually turns on the
type in one of the identity asserters that support it.
Look at the weblogic.security.spi.IdentityAsserter javadoc
for some standard token types.
On the other hand, if you have a custom token type that no
other identity asserter will ever implement, you may default the
active types attribute to include your token type. If you do,
then the adminstrator doesn't have to manually turn on your token
type.
Since the simple sample identity asserter's token type is very specific
to the sample (instead of a common type like X509), turn on the
token type by default.
-->
<MBeanAttribute

Default = "new String[] { "SamplePerimeterAtnToken" }"

<!-- Add any custom attributes for your provider here.
The simple sample identity asserter does not have any custom attributes.
Note: custom attributes do not appear in the
console in WLS 7.0. Use the admin command line tool
(java weblogic.Admin) to view and set their values.
Refer to the "Developing Security Services" manual

/**
* This class is a java program that is used to demonstrate
* perimeter authentication / identity assertion.
*
* Normally, the authenticators configured in WLS are
* responsible for authenticating users (eg. checking
* a password). If the user can be authenticated, then
* the authenticators put the user, and the user's groups,
* into the subject. The subject is used later on for
* access checks (authorization).
*
* When using perimeter authentication, someone calling
* WLS is responsible for authenticating the users. A
* token, containing info that identifies the user, is passed
* into WLS. The identity asserter extracts the user name from
* the token and makes it available to the authenticators.
* The authenticators, instead of authenticating the user,
* directly put the user and the user's groups, into the
* subject. Again, the subject is user later on for
* access checks (authorization).
*
* The perimeter authentication sample has the following parts:
*
* - A webapp that has a jsp which requires identity assertion.
* its pages can only be accessed by users or groups whose name
* is "SamplePerimterAtnUsers". The relative URL of this jsp
* to where WLS is running is
* "SamplePerimeterAtnWebApp/SamplePerimeterAtn.jsp".
*
* - A sample identity asserter who handles tokens whose
* type is "SamplePerimterAtnToken". The tokens are arrays
* of bytes containing a string in the form "username=someusername".
*
* - A sample authenticator that automatically creates a group
* named "SamplePerimeterAtnUsers" and the users
* "SamplePerimeterAtnUser1" (who is a member is
* "SamplePerimeterAtnUsers") and "SamplePerimeterAtnUser2"
* (who is not a member of "SamplerPerimeterAtnUsers").
*
* - This client that takes the WLS URL (eg. http://localhost:7001)
* and a user name (eg. SamplePerimeterAtnUser1) on the command line.
* The client addes "SamplePerimeterAtnWebApp/SamplePerimeterAtn.jsp"
* to the WLS URL to get the URL of the sample perimter atn jsp.
*
* This client creates a SamplePerimterAtnToken that contains the
* user name, puts the token in to a HTTP request header, then sends
* a HTTP GET request to the jsp. If the user is a member of the
* SamplePerimeterAtnUsers group, then access is granted to the
* page and its contents are returned. If not, access is denied
* and this client gets a 401 error. When access is granted, the
* jsp prints the subject (that contains the user name and the
* user's groups) into the page it returns and the client prints
* it out.
