Fastmail.fm ldap

FastMail.fm is a popular email service that offers a self-hosted option, and it also supports LDAP (Lightweight Directory Access Protocol) for directory services. Here's an overview of how FastMail.fm uses LDAP:

What is LDAP?

LDAP is a protocol used for accessing and managing directory services. It allows applications to query and modify directory information, such as user accounts, groups, and permissions.

How does FastMail.fm use LDAP?

FastMail.fm uses LDAP to integrate with external directory services, such as Active Directory (AD) or OpenLDAP. This allows administrators to manage user accounts, groups, and permissions centrally, and have those changes reflected in FastMail.fm.

Here are some ways FastMail.fm uses LDAP:

  1. User authentication: FastMail.fm uses LDAP to authenticate users against an external directory service. When a user logs in to FastMail.fm, the service queries the LDAP directory to verify the user's credentials.
  2. User management: FastMail.fm uses LDAP to retrieve user information, such as email addresses, names, and groups. This information is used to populate the FastMail.fm interface and to manage user permissions.
  3. Group management: FastMail.fm uses LDAP to manage group membership and permissions. When a user is added or removed from a group in the LDAP directory, the change is reflected in FastMail.fm.
  4. Permission management: FastMail.fm uses LDAP to manage permissions and access control. For example, administrators can use LDAP to grant or revoke access to specific features or folders.

LDAP configuration in FastMail.fm

To configure LDAP in FastMail.fm, you'll need to provide the following information:

  1. LDAP server URL: The URL of the LDAP server, including the protocol (e.g., ldap:// or ldaps://) and the server hostname or IP address.
  2. LDAP base DN: The base distinguished name (DN) of the LDAP directory.
  3. Bind DN and password: The DN and password of the LDAP account used to bind to the directory.
  4. Search base: The base DN of the LDAP directory to search for users and groups.
  5. User and group filters: Optional filters to specify which users and groups to include or exclude from the search.

Once you've configured LDAP in FastMail.fm, you can use the service to manage your email accounts and collaborate with others using the directory service.
