title: Authentication failed error in Python script to connect MongoDB server using pymodm
body: <p>The MongoDB server is hosted in a docker container. Created a super user with root permission to login using username and password. Using pymodm to connect to MongoDB server from Python script.</p>
  
  <p>I'm able to connect to the docker hosted MongoDB server from the shell as well as the Compass tool. The effort to connect and insert new items programatically using Python script fails with Authentication Failed error.</p>
  
  <p>The script is as follows:</p>
  
  <pre><code>from pymodm import connect
  from pymodm import MongoModel, fields
  import urllib.parse
  
  class Dummy(MongoModel):    
      email = fields.EmailField(primary_key=True)
      name = fields.CharField()
  
      class Meta:
          connection_alias = 'Mongo'
  
  # Establish a connection to the database.
  mongo_uri = "mongodb://monadmin:" + urllib.parse.quote("myPassword@123") + "@192.168.x.x:27017/Test"
  
  # Establish a connection to the database.
  def Connect2DB()
      try:
          #connect('mongodb://localhost:27017/PMOTest')
          connect(mongo_uri, alias="Mongo")
          print("db connection success")
          return True
      except:
          print("db connection failed")
          return False
  
  def Insert_record():
      try:
          Dummy(email="hello@test.com", name="test").save()     
          print("save success")
      except ex:
          print("save failed")
  
  
  if __name__ == "__main__":
      if Connect2DB():
          Insert_record()
  </code></pre>
  
  <p>The connection succeeds but the insert record is failing with the following error: pymongo.errors.OperationFailure: Authentication failed</p>
