JIT provisioning

[back-2-95]

When user logs in first time, user gets proviosioned and persisted on the database just fine.

But then I logout and login again and this exception comes:

An exception occurred while executing a query: SQLSTATE[23505]: Unique violation: 7 ERROR: duplicate key value violates unique constraint "uniq_8d93d649e7927c74"
DETAIL: Key (email)=(firstname.lastname@domain.tld) already exists.

Any idea what am I missing?

Problem exists yet after upgrading nbgrp/onelogin-saml-bundle (v2.0.2 => v2.1.0)

Ok, with AI I came to this solution and it seems to work:

@back-2-95 sorry for a long response.

You are using "saml" basic user provider, which only instantiates a user entity. At the same time you set persist_user: true that triggers entityManager->persist for that user.
Use "entity" user provider (see an example in JIT user provisioning section) if you need to load a user from a database when it already exists. When there is no user in a database it will be created by user factory.
