Hi Alexei – No there is a not a draft or plan to address this currently.  It has been discussed, and the working group decided for now that service providers can use a “returned” value of “request” for large attributes such as this.  This prevents the full value from being returned on most calls, but does not give a great solution if you want to retrieve the full list.

Also, this is one of the problems that the PATCH operation is trying to address.  This allows clients to update large attributes (adding or removing values) without having to read the entire attribute.

Subject: [scim] Pagination for large ​multi-valued attributes

​​
Hello,

SCIM defines "startIndex" and "count" pagination query parameters that allow to control the amount of returned resources.

SCIM protocol seems to represent pagination only for top level resources (e.g. /Users?startIndex=2&count=10) and does not address pagination for multi-valued attributes, like group membership.

Are there any plans/draft or recommendations how to handle such use cases?

---
Thank you,
Alexei
