Login Schema is the XML file that provides the structure to the form-based authentication. Users can use a wide range of authentication forms using a set of user interface constructs that are similar to basic HTML forms.

In nFactor authentications, authentication factors are chained together. Each factor can have different login schema pages or files. In some authentication scenarios, users can be presented with multiple logon screens. You can also have one login schema gather the information that can be passed on to multiple factors so that the latter factors do not have to display another login schema.

The login schema XML files are included with the Citrix ADC appliance in /nsconfig/loginschema/LoginSchema.

Create a login schema profile

  1. Navigate to Security > AAA > Login Schema.
  2. Click the Profiles tab, and then click Add.

  3. In Authentication Schema, click the pencil icon.

  1. Navigate to Security > AAA > Login Schema.
  2. Click the Policies tab, and then click Add.
  3. In Profile, select the login schema profile created earlier.
  4. In Rule, enter the default syntax expression and click Create.
