On Jewel we have rgw-user with UID - _sc and the same access key:

radosgw-admin metadata user info --uid _sc
{
    "user_id": "_sc",
    "display_name": "_sc",
    "email": "",
    "suspended": 0,
    "max_buckets": 0,
    "auid": 0,
    "subusers": [],
    "keys": [
        {
            "user": "_sc",
            "access_key": "_sc",
            "secret_key": "xxx" 
        }
    ],
…

This user was created in Hammer and everything works fine on Jewel to.
But, after upgrade to Luminous(12.2.3) this user receives “InvalidAccessKeyId”.

Radosgw-admin says:

radosgw-admin metadata user info --uid _sc
could not fetch user info: no user info saved

We can't remove, view or modify this user on Luminous.
