Description:

ldappool 3.0.0

A simple connector pool for python-ldap.
The pool keeps LDAP connectors alive and let you reuse them,
drastically reducing the time spent to initiate a ldap connection.
The pool has useful features like:

transparent reconnection on failures or server restarts
configurable pool size and connectors timeouts
configurable max lifetime for connectors
a context manager to simplify acquiring and releasing a connector

You need python-ldap in order to use this library

Quickstart
To work with the pool, you just need to create it, then use it as a
context manager with the connection method:
from ldappool import ConnectionManager

cm = ConnectionManager('ldap://localhost')

with cm.connection('uid=adminuser,ou=logins,dc=mozilla', 'password') as conn:
.. do something with conn ..
The connector returned by connection is a LDAPObject, that’s binded to the
server. See https://pypi.org/project/python-ldap/ for details on how to use a connector.
It is possible to check the state of the pool by representing the pool as a string:
from ldappool import ConnectionManager

cm = ConnectionManager('ldap://localhost', size=2)

.. do something with cm ..

print(cm)
This will result in output similar to this table:
+--------------+-----------+----------+------------------+--------------------+------------------------------+
| Slot (2 max) | Connected | Active | URI | Lifetime (600 max) | Bind DN |
+--------------+-----------+----------+------------------+--------------------+------------------------------+
| 1 | connected | inactive | ldap://localhost | 0.00496101379395 | uid=tuser,dc=example,dc=test |
| 2 | connected | inactive | ldap://localhost | 0.00532603263855 | uid=tuser,dc=example,dc=test |
+--------------+-----------+----------+------------------+--------------------+------------------------------+

ConnectionManager options
Here are the options you can use when instanciating the pool:

uri: ldap server uri [mandatory]
bind: default bind that will be used to bind a connector.
default: None
passwd: default password that will be used to bind a connector.
default: None
size: pool size. default: 10
retry_max: number of attempts when a server is down. default: 3
retry_delay: delay in seconds before a retry. default: .1
use_tls: activate TLS when connecting. default: False
timeout: connector timeout. default: -1
use_pool: activates the pool. If False, will recreate a connector
each time. default: True

The uri option will accept a comma or whitespace separated list of LDAP
server URIs to allow for failover behavior when connection errors are
encountered. Connections will be attempted against the servers in order,
with retry_max attempts per URI before failing over to the next server.
The connection method takes two options:

bind: bind used to connect. If None, uses the pool default’s.
default: None
passwd: password used to connect. If None, uses the pool default’s.
default: None
