Hi Thomas,
the LoginFormsProvider has method "setAttribute" . I think that in the
authenticator, you can use something like
context.form().setAttribute("foo", "bar");
when "context" is AuthenticationFlowContext passed to the authenticator.
Then in the template, the attribute "foo" can be directly referenced.
Does it working for you?

FreeMarkerLoginFormsProvider as shown below.
This is quite hacky but does it's job until I find a better way to do this.
Within my custom Authenticator:
private static final String MY_CUSTOM_ATTRIBUTE="my_custom_attribute";
@Override
public void authenticate(AuthenticationFlowContext context) {
HttpServletRequest request =
context.getSession().getContext().getContextObject(HttpServletRequest.class);
try {
request.setAttribute(MY_CUSTOM_ATTRIBUTE, "bubu");
super.authenticate(context);
} finally {
request.removeAttribute(MY_CUSTOM_ATTRIBUTE);
}
}
Small extension to the FreeMarkerLoginFormsProvider in "private Response
createResponse(LoginFormsPages page)":
...
HttpServletRequest currentHttpRequest =
session.getContext().getContextObject(HttpServletRequest.class);
if (currentHttpRequest != null) {
attributes.put("currentRequestAttributes", new
HttpServletRequestAttributesBean(currentHttpRequest));
}
...
public static class HttpServletRequestAttributesBean {
private final HttpServletRequest request;
public HttpServletRequestAttributesBean(HttpServletRequest request){
this.request = request;
}
public Object getAttribute(String name){
return this.request.getAttribute(name);
}
public Map<String,Object> getAttributes(){
Map<String,Object> attributes = new HashMap<>();
for(String name : Collections.list(request.getAttributeNames())){
attributes.put(name, request.getAttribute(name));
}
return attributes;
}
}
In my template login-totp.ftl:
<span>Custom value:
${currentRequestAttributes.getAttribute('my_custom_attribute')!'default'}</span>
