[Using Sakai] user IDs

[Gregory Guthrie]

Thank you; yes, seems to be related to how a developer may create extensions to do this if I read the notes right.

One note states that: "Sakai has two identifiers for a user:  an internal id, and an institutional id",
In Sakai I see; name, user_id, and email, and somewhere else an internal ID.
What is the "institutional ID" and where is it set, shown?

I see a participant ID field on Site Info (not in Roster or Gradebook), how does this get set?
(Although Roster has User-ID, which is (for us) an email, and seems different).
Admin:Users shows an Internal-ID (32-byte) identifier, also something different I think.

Since these notes are pretty old (2007,09), I guess that means this would still be a DIY extension?
I'm not sure how one would use a code extension like this - are there guidelines somewhere for incorporating such extensions?
(perhaps I need to ask in a developers forum?)

Could you comment on:
