Authentication
Choosing the Authentication Method
With Icinga Web 2 you can authenticate against Active Directory, LDAP, a MySQL or a PostgreSQL database or delegate authentication to the web server.
Authentication methods can be chained to set up fallback authentication methods or if users are spread over multiple places.
Configuration
Authentication methods are configured in the INI file config/authentication.ini.
Each section in the authentication configuration represents a single authentication method.
The order of entries in the authentication configuration determines the order of the authentication methods. If the current authentication method errors or if the current authentication method does not know the account being authenticated, the next authentication method will be used.
External Authentication
For delegating authentication to the web server simply add autologin to your authentication configuration:
[autologin]
backend = autologin
If your web server is not configured for authentication though the autologin section has no effect.
Active Directory or LDAP Authentication
If you want to authenticate against Active Directory or LDAP, you have to define a LDAP resource which will be referenced as data source for the Active Directory or LDAP configuration method.
LDAP
| Directive | Description |
|---|---|
| backend | ldap |
| resource | The name of the LDAP resource defined in resources.ini. |
| user_class | LDAP user class. |
| user_name_attribute | LDAP attribute which contains the username. |
Example:
[auth_ldap]
backend = ldap
resource = my_ldap
user_class = inetOrgPerson
user_name_attribute = uid
Active Directory
| Directive | Description |
|---|---|
| backend | ad |
| resource | The name of the LDAP resource defined in resources.ini. |
Example:
[auth_ad]
backend = ad
resource = my_ad
Database Authentication
If you want to authenticate against a MySQL or a PostgreSQL database, you have to define a database resource which will be referenced as data source for the database authentication method.
| Directive | Description |
|---|---|
| backend | db |
| resource | The name of the database resource defined in resources.ini. |
Example:
[auth_ad]
backend = ad
resource = icingaweb-mysql
Database Setup
For authenticating against a database, you have to import one of the following database schemas:
- etc/schema/preferences.mysql.sql (for MySQL database)
- etc/schema/preferences.pgsql.sql (for PostgreSQL databases)
After that you have to define the database resource.
Manually Creating Users
Icinga Web 2 uses the MD5 based BSD password algorithm. For generating a password hash, please use the following command:
openssl passwd -1 "password"
Note: The switch to
openssl passwdis the number one (-1) for using the MD5 based BSD password algorithm.
Insert the user into the database using the generated password hash:
INSERT INTO icingaweb_user (name, active, password_hash) VALUES ('icingaadmin', 1, 'hash from openssl');
