davidszotten/devpi-ldap

Plugin for devpi-server which provides LDAP authentication.

devpi-ldap: LDAP authentication for devpi-server

For use with devpi-server >= 2.1.0.

Installation

devpi-ldap needs to be installed alongside devpi-server.

You can install it with:

pip install devpi-ldap

For devpi-server there is no configuration needed, as it will automatically discover the plugin through calling hooks using the setuptools entry points mechanism.

Details about LDAP configuration below.

Configuration

A script named devpi-ldap can be used to test your LDAP configuration.

To configure LDAP, create a yaml file with a dictionary containing another dictionary under the devpi-ldap key with the following options:

url

The url of the LDAP server. Using ldaps:// enables SSL. No certificate validation is performed at the moment.

user_template

The template to generate the distinguished name for the user. If the structure is fixed, this is faster than specifying a user_search, but devpi-server can't know whether a user exists or not.

user_search

If you can't or don't want to use user_template, then these are the search settings for the users distinguished name. You can use username in the search filter. See specifics below.

group_search

The search settings for the group objects of the user. You can use username and userdn (the distinguished name) in the search filter. See specifics below.

referrals

Whether to follow referrals. This needs to be set to false in many cases when using LDAP via Active Directory on Windows. The default is true.

The user_search and group_search settings are dictionaries with the following options:

base

The base location from which to search.

filter

The search filter. To use replacements, put them in curly braces. Example: (&(objectClass=group)(member={userdn}))

scope

The scope for the search. Valid values are base-object, single-level and whole-subtree. The default is whole-subtree.

attribute_name

The name of the attribute which should be extracted from the search result.

userdn

The distinguished name of the user which should be used for the search operation. If you don't have anonymous user search or if the users can't search their own groups, then you need to set this to a user which has the necessary rights.

password

The password for the user in userdn.

The YAML file should then look similar to this:

---
devpi-ldap:
  url: ldap://example.com
  user_template: CN={username},CN=Partition1,DC=Example,DC=COM
  group_search:
    base: CN=Partition1,DC=Example,DC=COM
    filter: (&(objectClass=group)(member={userdn}))
    attribute_name: CN

An example with user search and Active Directory might look like this:

---
devpi-ldap:
  url: ldap://example.com
  user_search:
    base: CN=Partition1,DC=Example,DC=COM
    filter: (&(objectClass=user)(sAMAccountName={username}))
    attribute_name: distinguishedName
  group_search:
    base: CN=Partition1,DC=Example,DC=COM
    filter: (&(objectClass=group)(member={userdn}))
    attribute_name: CN
