Two same users in sharing tab

Hello,
User in Sharing tab sees two entries of the same person.

  • One of them is with avatar and regular. In my account I see it too. (Let’s say “Alex” entry)
  • Second has no avatar and has name like “Alex(remote)”

Why does it duplicated? What might “remote” mean?
No one can reproduce it on that server and there is only one entry in oc_ldap_user_mapping for this user. It’s not duplicated in oc_user. SAML isn’t configured.

When both selected, there are problems in granting access option to them (create/update/delete in folder or etc).

I found it was connected to Federation app. As we don’t use it, I disabled this feature and remote user disappeared.
