Steps to Reproduce:
1. Create a user 'testx$tester' in a tenant
2. Create another user 'testx$testabc' in the same tenant with the same 'access_key' name but different 'secret_key'

Actual results:
The command succeeds, but there is no user by name u2 created. Instead, it replaces the existing u1's access-key and secret-key

Additional info:
Users before creating 'testx$testabc'

    "testy$test",
    "testx$test1",
    "testuser",
    "testy$tester",
    "testx$tester",
    "synchronization-user" 

Existing user:

# radosgw-admin user info --tenant testx --uid tester --cluster ceph1

{
    "user_id": "testx$tester",
    "display_name": "Test User",
    "email": "",
    "suspended": 0,
    "max_buckets": 1000,
    "auid": 0,
    "subusers": [],
    "keys": [
        {
            "user": "testx$tester",
            "access_key": "TESTER",
            "secret_key": "test123" 

Create new user 'testabc' with same access_key:

# radosgw-admin --tenant testx --uid testabc --display-name "Test User" --access_key TESTER --secret testabc user create --cluster ceph1

{
    "user_id": "testx$tester", -------> created with a wrong user id 'tester'
    "display_name": "Test User",
    "email": "",
    "suspended": 0,
    "max_buckets": 1000,
    "auid": 0,
    "subusers": [],
    "keys": [
        {
            "user": "testx$tester",
            "access_key": "TESTER",
            "secret_key": "testabc" 
        }

The output shows that a user is created. But it is actually replacing the existing user 'testx$tester' secret_key with the the new user's secret_key

# radosgw-admin user info --tenant testx --uid testabc --cluster ceph1
could not fetch user info: no user info saved

# radosgw-admin user info --tenant testx --uid tester --cluster ceph1

{
    "user_id": "testx$tester",
    "display_name": "Test User",
    "email": "",
    "suspended": 0,
    "max_buckets": 1000,
    "auid": 0,
    "subusers": [],
    "keys": [
        {
            "user": "testx$tester",
            "access_key": "TESTER",
            "secret_key": "testabc" --------> the secret_key is replaced 
        }

Expected result:
The user create command should have failed and not replace the secret_key of another user.
