authentication

Configures how Radiator authenticates (binds) to the LDAP server. This block is placed inside a server block. If omitted, Radiator connects anonymously.

Two mutually exclusive authentication modes are supported:

Simple bind (dn / password)

Authenticates with a distinguished name and password. This is the most common mode.

Parameter	Required	Description
`dn`	Yes	Distinguished name to bind as. Accepts a literal string or environment variable reference.
`password`	Yes	Bind password. Accepts a literal string or environment variable reference.

server "ldap.example.com" {
    url "ldap://ldap.example.com:389/";
    authentication {
        dn "cn=read-only-admin,dc=example,dc=com";
        password "password";
    }
}

Credentials can be sourced from environment variables:

authentication {
        dn env.LDAP_BIND_DN;
        password env.LDAP_BIND_PW;
}

SASL External

Authenticates using the TLS client certificate presented during the TLS handshake (SASL EXTERNAL mechanism). Requires a tls block with a client certificate on the same server.

server "ldaps.example.com" {
    url "ldaps://ldaps.example.com:636/";
    tls {
        certificate "ldap-client.cert";
        certificate_key "ldap-client.key";
        server_ca_certificate "ldap-ca.cert";
    }
    authentication {
        external;
    }
}
