FreeIPA

Support level: Community

Preparation​

The following placeholders will be used:

  • svc_authentik is the name of the bind account.
  • freeipa.company is the Name of the domain.
  • ipa1.freeipa.company is the Name of the FreeIPA server.

FreeIPA Setup​

  1. Log into FreeIPA.

  2. Create a user in FreeIPA, matching your naming scheme. Provide a strong password, example generation methods: pwgen 64 1 or openssl rand -base64 36. Once done click Add and Edit.

  3. In the user management screen, select the Roles tab.

  4. Add a role that has privileges to change user passwords, the default User Administrators role is sufficient. This is needed to support password resets from within authentik.

  5. By default, if an administrator account resets a user's password in FreeIPA the user's password expires after the first use and must be reset again. This is a security feature to ensure password complexity and history policies are enforced. To bypass this feature for a more seamless experience, you can make the following modification on each of your FreeIPA servers:

    $ ldapmodify -x -D "cn=Directory Manager" -W -h ipa1.freeipa.company -p 389

    dn: cn=ipa_pwd_extop,cn=plugins,cn=config
    changetype: modify
    add: passSyncManagersDNs
    passSyncManagersDNs: uid=svc_authentik,cn=users,cn=accounts,dc=freeipa,dc=company

authentik Setup​

In authentik, create a new LDAP Source in Resources -> Sources.

Use these settings:

  • Server URI: ldaps://ipa1.freeipa.company

    You can specify multiple servers by separating URIs with a comma, like ldap://ipa1.freeipa.company,ldap://ipa2.freeipa.company.

    When using a DNS entry with multiple Records, authentik will select a random entry when first connecting.

  • Bind CN: uid=svc_authentik,cn=users,cn=accounts,dc=freeipa,dc=company

  • Bind Password: The password you've given the user above

  • Base DN: dc=freeipa,dc=company

  • Property mappings: Control/Command-select all Mappings which start with "authentik default LDAP" and "authentik default OpenLDAP"

  • Group property mappings: Select "authentik default OpenLDAP Mapping: cn"

Additional settings:

  • Group: If selected, all synchronized groups will be given this group as a parent.

  • Addition User/Group DN: cn=users,cn=accounts

  • Addition Group DN: cn=groups,cn=accounts

  • User object filter: (objectClass=person)

  • Group object filter: (objectClass=groupofnames)

  • Group membership field: member

  • Object uniqueness field: ipaUniqueID

After you save the source, you can kick off a synchronization by navigating to the source, clicking on the "Sync" tab, and clicking the "Run sync again" button.

Lastly, verify that the "User database + LDAP password" backend is selected in the "Password Stage" under Flows -> Stages.
