The oid of the user that returns the ESIA has changed, what should I do?

Question

PHP

In general, the site works with authorization through the ESIA system. They changed the policy and the list of organizations the user stopped coming in general information, implemented a subquery that additionally pulls organizations, but after the release it turned out that the user had changed oid. And since this is the only way to match the ESIA user with the user on our site, a new user is created. Why did the user's oid change and how to prevent this from happening?

Answer 1

The easiest one is to link to Inn. If it is possible to draw the Inn, then there will be no problems with the comparison.
