[BUG] Azure SSO creates a new user after each login

[pavlushkin]

Describe the bug
I configured IdentityProvider for Azure AD:

scopes:
  - profile
  - openid
system: az-dev
userinfo_endpoint: https://graph.microsoft.com/oidc/userinfo
authorize_endpoint: >-
  https://login.microsoftonline.com/7d4edb64/oauth2/v2.0/authorize
client:
  id: 07c17587
  secret: AW78Q
resourceType: IdentityProvider
title: Azure AD
active: true
id: azure-ad-dev
token_endpoint: >-
  https://login.microsoftonline.com/7d4edb64/oauth2/v2.0/token

Login with Azure ID works,
but after each login as admin I see a new user created.

User:

data:
  sub: 1smMdvcWP876Y6d
  name: Aaa
  email: test@.onmicrosoft.com
  picture: https://graph.microsoft.com/v1.0/me/photo/$value
  given_name: Aa
  family_name: Bb
identifier:
  - value: 1smMdvcWP87
    system: az-dev
id: 12b44fd6-db22-4f07-b3e1-3dee45506365
resourceType: User
