Flask-SimpleLDAP provides LDAP authentication for Flask.

First, install Flask-SimpleLDAP:

$ pip install flask-simpleldap

Flask-SimpleLDAP depends, and will install for you, recent versions of Flask (0.9 or later) and python-ldap. Flask-SimpleLDAP is compatible with and tested on Python 2.6 and 2.7.

Next, add a LDAP instance to your code and at least the three required configuration options:

from flask import Flask
from flask.ext.simpleldap import LDAP

app = Flask(__name__)
ldap = LDAP(app)

app.config['LDAP_BASE_DN'] = 'OU=users,dc=example,dc=org'
app.config['LDAP_USERNAME'] = 'CN=user,OU=Users,DC=example,DC=org'
app.config['LDAP_PASSWORD'] = 'password'

@app.route('/ldap')
@ldap.login_required
def ldap_protected():
    return 'Success!'

You can take a look at examples/groups for a more complete example using LDAP groups.

You can also take a look at examples/blueprints for an example using Flask's application factories and blueprints.
