我已经安装了 Davical 1.1.1 并且使用默认身份验证工作正常。我正在尝试使用 OpenLDAP 2.3 服务器启用 LDAP 身份验证。身份验证似乎工作正常（日志显示我从 LDAP 服务器获取了正确的名称和电子邮件地址），但是当 Davical 尝试创建新用户时出现数据库错误。无论我尝试使用 LDAP 凭据登录 Web 面板还是以管理员身份登录并使用“工具”页面同步 LDAP 用户，都会发生同样的事情。
这是来自 LDAP 登录尝试的日志：

这里似乎有两个错误 - 一个是在尝试为用户创建主体时，另一个是在尝试创建默认集合集时。在后一种情况下，主体似乎没有返回“user_no”的值以用于新集合。
Davical LDAP 文档 ( http://wiki.davical.org/w/Configuration/LDAP ) 表明“user_no”的映射字段应该对应 LDAP 中的 Unix uid，但我们的 LDAP 服务器不使用 uid 号，所以我从配置文件中删除了这个映射。这是当前配置的样子（更改了域名以保护无辜者）：
<?php
$c->domain_name = "calendar.myserver.com";
$c->admin_email = 'webmaster@myserver.com';
$c->pg_connect[] = 'dbname=davical port=5432 user=davical_app';
$c->authenticate_hook['call'] = 'LDAP_check';
$c->do_not_sync_from_ldap = array('admin' => true);
$c->authenticate_hook['config'] = array(
'host' => 'ldaps://www.myserver.com:636', //host name of your LDAP Server
'bindDN' => 'cn=Manager,dc=myserver,dc=com', //DN to bind request to this server (if required)
'passDN' => 'nice_try', //Password of request bind
'baseDNUsers' => 'ou=people,dc=myserver,dc=com', //where to look for valid user
'filterUsers' => 'objectClass=inetOrgPerson', //filter which must validate a user according to RFC4515, i.e. surrounded by brackets
'protocolVersion' => 3, // important for simple auth (no sasl)
'mapping_field' => array(
'username' => 'uid',
'modified' => 'modifyTimestamp',
'fullname' => 'cn', // "Common Name"
'email' => 'mail'), //used to create the user based on his LDAP properties
'format_updated'=> array('Y' => array(0,4),
'm' => array(4,2),
'd' => array(6,2),
'H' => array(8,2),
'M' => array(10,2),
'S' => array(12,2)), // map LDAP "modifyTimestamp" field to SQL "updated" field
'scope' => 'subtree' // Search scope to use, defaults to subtree ( applies to BOTH user and group mappings )
// Allowed values: base, onelevel, subtree.
);

这是 Davical 1.1.1 中的错误，还是我做错了什么？
