//
// Enable oidentd support using the specified file
//
// Example: oidentd: "~/.oidentd.conf",
//
// @type string
// @default null
// When this setting is a string, this enables `oidentd` support using the

// These settings enable and configure LDAP authentication.

// LDAP authentication settings (only available if public=false)
// @type object
// @default {}
// They are only being used in private mode. To know more about private mode,

// 2. It performs an LDAP search query to find the full DN associated to the

// to be returned;
// be returned;
// - a search scope `searchDN/scope` (see LDAP documentation);
// - the query itself, build as (&(<primaryKey>=<username>) <filter>)
// where <username> is the user name provided in the log in request,
// <primaryKey> is provided by the config and <fitler> is a filtering complement
// also given in the config, to filter for instance only for nodes of type

//
// Alternatively, you can specify the `bindDN` parameter. This will make the lounge
