Configuring user authentication¶

The LAVA frontend is developed using the Django web application framework and user authentication and authorization is based on the standard Django auth subsystems. This means that it is fairly easy to integrate authentication against any source for which a Django backend exists. Discussed below are the tested and supported authentication methods for LAVA.

Note

LAVA used to include support for OpenID authentication (prior to version 2016.8), but this support had to be removed when incompatible changes in Django (version 1.8) caused it to break.

Local Django user accounts are supported. When using local Django user accounts, new user accounts need to be created by Django admin prior to use.

Using Lightweight Directory Access Protocol (LDAP)¶

LAVA server may be configured to authenticate via Lightweight Directory Access Protocol (LDAP). LAVA uses the django_auth_ldap backend for LDAP authentication.

LDAP server support is configured using the following parameters in /etc/lava-server/settings.conf (JSON syntax):

"AUTH_LDAP_SERVER_URI": "ldap://ldap.example.com",
"AUTH_LDAP_BIND_DN": "",
"AUTH_LDAP_BIND_PASSWORD": "",
"AUTH_LDAP_USER_DN_TEMPLATE": "uid=%(user)s,ou=users,dc=example,dc=com",
"AUTH_LDAP_USER_ATTR_MAP": {
  "first_name": "givenName",
  "email": "mail"
},

Use the following parameter to configure a custom LDAP login page message:

"LOGIN_MESSAGE_LDAP": "If your Linaro email is first.second@linaro.org then use first.second as your username"

Other supported parameters are:

"AUTH_LDAP_GROUP_SEARCH": "LDAPSearch('ou=groups,dc=example,dc=com', ldap.SCOPE_SUBTREE, '(objectClass=groupOfNames)'",
"AUTH_LDAP_USER_FLAGS_BY_GROUP": {
  "is_active": "cn=active,ou=django,ou=groups,dc=example,dc=com",
  "is_staff": "cn=staff,ou=django,ou=groups,dc=example,dc=com",
  "is_superuser": "cn=superuser,ou=django,ou=groups,dc=example,dc=com"
}

Similarly:

"AUTH_LDAP_USER_SEARCH": "LDAPSearch('o=base', ldap.SCOPE_SUBTREE, '(uid=%(user)s)')"

Note

If you need to make deeper changes that don’t fit into the exposed configuration, it is quite simple to tweak things in the code here. Edit /usr/lib/python3/dist-packages/lava_server/settings/common.py

Restart the lava-server and apache2 services after any changes.
