Public bug reported:

/services?name=<name> API can't find the service when using list_limit configuration.
Before setting list_limit in keystone.conf the following API call behaves correctly: 

stack@mitaka2:/opt/stack/keystone$ curl -H "X-Auth-Token: $TOK" http://mitaka2.com:5000/v3/services?name=keystone | python -mjson.tool
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   318  100   318    0     0     95      0  0:00:03  0:00:03 --:--:--    95
{
    "links": {
        "next": null,
        "previous": null,
        "self": "http://mitaka2.com/identity/v3/services?name=keystone";
    },
    "services": [
        {
            "enabled": true,
            "id": "f7ef63607b8542e0a7cb9a9b1b119c25",
            "links": {
                "self": "http://mitaka2.com/identity/v3/services/f7ef63607b8542e0a7cb9a9b1b119c25";
            },
            "name": "keystone",
            "type": "identity"
        }
    ]
}

After setting list_limit=3 in the Default section in keystone.conf, the
API can't find the service any more:

stack@mitaka2:/opt/stack/keystone$ curl -H "X-Auth-Token: $TOK" http://mitaka2.com:5000/v3/services?name=keystone | python -mjson.tool
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   143  100   143    0     0     43      0  0:00:03  0:00:03 --:--:--    43
{
    "links": {
        "next": null,
        "previous": null,
        "self": "http://mitaka2.com/identity/v3/services?name=keystone";
    },
    "services": [],
    "truncated": true
}

It seems like the list is truncated before applying the name filter.
