 | `ckanext.ldap.allow_password_reset` | If true, allows LDAP users to reset their passwords, if false, disallows this functionality. Note that if this is true, the password that is reset is the CKAN user password, not the LDAP one. If set to false, the request to reset will be denied only if the user is an LDAP user, if not they will be allowed to reset regardless of the value of this option.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     | True/False                      | true     |

+| `ckanext.ldap.ignore_referrals`     | If true, The plugin will ignore referral query results sent by the LDAP server. This might be necessary if your base_dn is at the domain level, but the LDAP server searches in multiple paths for the user, resulting in queries containing more than one result.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     | True/False                      | false     |
