[python3-ldap] Connection Slowness

[Derrick Jackson]

Hi Giovanni,

Thanks for the quick follow-up.  I was up until a moment ago using
python3-ldap.  I am using ldap3 now.  However I am still finding that
authentication and search are taking a bit longer to respond.  Here is the
flow I am following.

1.  User hits the login page and sends credentials and enters their email
address and password.
2.  A generic account logs into Active Directory and searches for that
user.  If found, that user's information is returned and the connection is
closed.
3.  We then create another connection and authenticate the user based on
the username returned from step2.  Once authenticated the user is allowed
access to the application.
4.  This process takes ~16-25 seconds to complete.

I decided to test this outside of my web application so i went to the
python interpreter, imported ldap3 and did the following:

AD_URL = 'host:636'
PORT = 636

s = Server(AD_URL, get_info=None, use_ssl=True)
c = Connection(s, auto_bind=True, user='domain\username', password=password)

This process took about 6 seconds to complete.  I am trying to understand
where the choke point is right now.  Just wondering if it is our ldap
server or something else.
