Configuration and connecting – How to configure Net_LDAP2 and connect to an LDAP server
Connecting to an LDAP server
To connect to an LDAP server, you should use Net_LDAP2's static connect() method. It takes one parameter, an array full of configuration options, and either returns a Net_LDAP2 object if connecting works, or a Net_LDAP2_Error object in case of a failure.
The following table lists all configuration options. If the default value for an option fits your needs, you don't need add it to your configuration array.
| Name | Описание | Default |
|---|---|---|
host |
LDAP server name to connect to. You can provide several hosts in an array in which case the hosts are tried from left to right. | localhost |
port |
Port on the server | 389 |
version |
LDAP version | 3 |
starttls |
TLS is started after connecting | false |
binddn |
The distinguished name to bind as (username). If you don't supply this, an anonymous bind will be established. | (none) |
bindpw |
Password for the binddn. If the credentials are wrong, the bind will fail server-side and an
anonymous bind will be established instead. An empty bindpw string requests an unauthenticated bind. This can cause
security problems in your application, if you rely on a bind to make security decisions (see
RFC-4513, section 6.3.1). |
(none) |
basedn |
LDAP base name (root directory) | (none) |
options |
Array of additional ldap options as key-value pairs | array() |
filter |
Default search filter (string or preferably Net_LDAP2_Filter object). See LDAP filters | (objectClass=*) |
scope |
Default search scope, see Search | sub |
