Hi Simon, [Configure Registration from Attributes](https://gluu.org/docs/oxtrust/configuration/#manage-registration) is the feature where you can define specific attributes for registration page.

Simon, One thing to note is that if possible, we recommend handling registration in your app locally, then pushing the information to the Gluu Server via SCIM. This will give you much more control and flexibility in defining the exact registration process you want users to go through. In fact, we're getting ready to push updates to this support app that will follow the same guidance. Thanks, Will

Hi Mohib, That's not quite the effect I'm after. What you've described allows the user to complete more information during registration (and I can indeed add my custom attribute to the list as you've described). What I want to do, is set the value as part of the user registration script. It's a field that should be set for these users, but which they should not be able to set themselves as it's used downstream for an application permission. In the end I had a look at the [source for gluuCustomPerson.java](https://github.com/GluuFederation/oxTrust/blob/e03407f0133ffbd3dd9d0c1c585a2b0c9ed45d96/server/src/main/java/org/gluu/oxtrust/model/GluuCustomPerson.java) to figure out what operations are permitted then added the following to the preRegistration element of the User Registration custom script. ``` user.setAttribute("myCustomAttributeName","myStringValue") ``` Works like a charm :) William, That sounds good for longer term but would have been a pain for a like-for-like swap from ADFS (my case)

Great. Thanks for the feedback, Simon.
