galdanwing / getsentry-ldap-auth

A Sentry extension to add an LDAP server as an authention source.

sentry-ldap-auth

A Django custom authentication backend for Sentry. This module extends the functionality of django-auth-ldap with Sentry specific features.

Features

• Users created by this backend are managed users. Managed fields are not editable through the Sentry account page.
• Users may be auto-added to an Organization upon creation.

Prerequisites

Versions 2.0 and newer require Sentry 8. For Sentry 7 support, use the 1.1 release

Installation

To install, simply add sentry-ldap-auth to your requirements.txt in your Sentry environment and install gcc in your Dockerfile in the same config

RUN apt-get update && apt-get install -y gcc

Configuration

This module extends the django-auth-ldap and almost all the options are supported (up until 1.7.*) One options that's not supported is AUTH_LDAP_MIRROR_GROUPS .

To configure Sentry to use this module, add sentry_ldap_auth.backend.SentryLdapBackend to your AUTHENTICATION_BACKENDS in your sentry.conf.py, like this:

AUTHENTICATION_BACKENDS = AUTHENTICATION_BACKENDS + (
    'sentry_ldap_auth.backend.SentryLdapBackend',
)

Then, add any applicable configuration options. Depending on your environment, and especially if you are running Sentry in containers, you might consider using python-decouple so you can set these options via environment variables.

sentry-ldap-auth Specific Options

AUTH_LDAP_DEFAULT_SENTRY_ORGANIZATION = u'My Organization Name'

Auto adds created user to the specified organization (matched by name) if it exists.

AUTH_LDAP_SENTRY_ORGANIZATION_ROLE_TYPE = 'member'

Role type auto-added users are assigned. Valid values in a default installation of Sentry are 'member', 'admin', 'manager' & 'owner'. However, custom roles can also be added to Sentry, in which case these are also valid.

AUTH_LDAP_SENTRY_ORGANIZATION_GLOBAL_ACCESS = True

Whether auto-created users should be granted global access within the default organization.

AUTH_LDAP_SENTRY_SUBSCRIBE_BY_DEFAULT = False

Whether new users should be subscribed to any new projects by default. Disabling this is useful for large organizations where a subscription to each project might be spammy.

AUTH_LDAP_SENTRY_USERNAME_FIELD = 'uid'

Specify which attribute to use as the Sentry username, if different from what the user enters on the login page. You can use this to prevent multiple accounts from being created when your AUTH_LDAP_USER_SEARCH allows users to log in with different usernames (e.g. (|(uid=%(user))(mail=%(user)))). If multiple values exist for the attribute, the first value will be used.

AUTH_LDAP_DEFAULT_EMAIL_DOMAIN = 'example.com'

Default domain to append to username as the Sentry user's e-mail address when the LDAP user has no mail attribute.

Sentry Options

SENTRY_MANAGED_USER_FIELDS = ('email', 'first_name', 'last_name', 'password', )

Fields which managed users may not modify through the Sentry accounts view. Applies to all managed accounts.
