Defining References to Authentication Schemes 

Use

A reference to an authentication scheme is a ‘pointer’ to an authentication scheme. All iViews and iView templates shipped with the portal have a property that contains a reference to an authentication scheme. By changing what the reference points to (that is, by modifying a reference to an authentication scheme), you can change the authentication scheme for a whole set of iViews and iView templates without having to change the property in each individual iView or iView template.

All Web Dynpro applications use the authentication scheme referenced by default. By changing the authentication scheme that default points to, you change the authentication scheme for all Web Dynpro applications.

Procedure

Open the file authschemes.xml for modifying as described in Changing the authschemes.xml File.

The first part of this file contains a list of authentication schemes. At the end of the file you can define references to authentication schemes. The following is an example:

<!--  References for Authentication Schemes, -->     <!--  this section must be after authschemes -->     <authscheme-refs>         <authscheme-ref name="default">             <authscheme>uidpwdlogon</authscheme>         </authscheme-ref>     </authscheme-refs>

In the above example, the reference default points to the authentication scheme called uidpwdlogon that is defined in the same file. All applications that are assigned to the authentication scheme reference default require the uidpwdlogon authentication scheme. By changing uidpwdlogon to basicauthentication,for example, all the iView templates that are assigned to default now require the basicauthentication authentication scheme.

When you are finished editing authschemes.xml, save the file and proceed as described in Changing the authschemes.xml File.
