The IBM Security Access Manager Web Security Developer Reference
provides programming information and references for developing authentication
modules using the external authentication C API. It also includes
instructions for developing authentication modules that provide cross-domain
single sign-on authentication and e-community single sign-on. The
use of the cross-domain mapping framework to enhance cross-domain
single sign-on and e-community single sign-on is also described. The
document contains the API references for the external authentication
C API and the cross-domain mapping framework API.
