Custom authentication

Setup FreeIPA authentication

You can configure LibreTime to delegate all authentication to a FreeIPA server.

This allows you users to use their existing FreeIPA credentials. For this to work you need to configure Apache to use mod_authnz_pam and mod_intercept_form_submit.

Apache configuration

After installing the needed modules you can set up Apache to intercept form logins and check them against pam.

<Location /login>
InterceptFormPAMService http-libretime
InterceptFormLogin username
InterceptFormPassword password
InterceptFormLoginSkip admin
InterceptFormPasswordRedact on
InterceptFormLoginRealms INT.RABE.CH
Require pam-account http-libretime

<Location />
Require pam-account http-libretime
Require all granted
Require expr %{REQUEST_URI} =~ /(index.php|login|favicon.ico|js|css|locale)/
Require all granted

PAM configuration

The above configuration expects a PAM configuration for the http-libretime service.

To confiure this you need to create the file /etc/pam.d/http-libretime with the following contents.

auth    required
account required

LDAP configuration

LibreTime needs direct access to LDAP so it can fetch additional information. It does so with a system account that you need to set up beforehand.

You can configure everything pertaining to how LibreTime accesses LDAP in /etc/libretime/config.yml. The default file has the following values you need to change.

# ----------------------------------------------------------------------
# L D A P
# ----------------------------------------------------------------------
# hostname: Hostname of LDAP server
# binddn: Complete DN of user used to bind to LDAP
# password: Password for binddn user
# account_domain: Domain part of username
# basedn: base search DN
# filter_field: Name of the uid field for searching
# Usually uid, may be cn
# groupmap_*: Map LibreTime user types to LDAP groups
# Lets LibreTime assign user types based on the
# group a given user is in.
binddn: "uid=libretime,cn=sysaccounts,cn=etc,dc=int,dc=example,dc=org"
password: hackme
account_domain: INT.EXAMPLE.ORG
basedn: "cn=users,cn=accounts,dc=int,dc=example,dc=org"
filter_field: uid
groupmap_guest: "cn=guest,cn=groups,cn=accounts,dc=int,dc=example,dc=org"
groupmap_host: "cn=host,cn=groups,cn=accounts,dc=int,dc=example,dc=org"
groupmap_program_manager: "cn=program_manager,cn=groups,cn=accounts,dc=int,dc=example,dc=org"
groupmap_admin: "cn=admins,cn=groups,cn=accounts,dc=int,dc=example,dc=org"
groupmap_superadmin: "cn=superadmin,cn=groups,cn=accounts,dc=int,dc=example,dc=org"

Enable FreeIPA authentication

After everything is set up properly you can enable FreeIPA auth in config.yml:

auth: LibreTime_Auth_Adaptor_FreeIpa

You should now be able to use your FreeIPA credentials to log in to LibreTime.
