          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.11.0
         Environment: python: 3.6.6

impyla: 0.14.1

I enable ldap user authentication for impalad. I run the following code to test impalad stability, and I find when I run ten thousand times, the following error will occur two times in impalad.INFO log file.

test code:

```python

import impala.dbapi

test_conf = {
 'host': '172.16.24.xx',
 'port': 21050,
 'user': 'xxxx',
 'password': 'xxxxx'
}


def test_impala(conf):
      conn = impala.dbapi.connect(**conf)

      conn.close()

 

N = 10000

for i in range(N):

      test_impala(test_conf)

```

error info:

```

I0204 15:41:40.600821 168276 thrift-util.cc:123] TAcceptQueueServer: Caught TException: invalid sasl status

```

When this error occurs, the connect request will hang for one minute or two minutes, and all subsequent connect request including request from hue will hang too.
