Which of the following are common Net::LDAP methods? (Choose THREE correct answers.)

The `bind` method is fundamental in `Net::LDAP` for authenticating to the LDAP server, which is typically the first step before performing most other directory operations.

`query` is not a standard `Net::LDAP` method; LDAP operations for retrieving data are typically named `search`.

`error` is a common method name in many programming contexts to retrieve error information, but it is not a primary `Net::LDAP` *operation* method for interacting with the directory itself.

The `search` method is used to query the LDAP directory for entries that match specified criteria, retrieving data from the directory server based on filters and base DNs.

The `unbind` method is used to gracefully close the connection to the LDAP server, releasing resources and terminating the LDAP session after operations are complete.
