redmine设置ldap认证，ldap帐号无法登录

hivhhy

redmine界面设置ldap认证，test连接成功，但是ldap帐号无法登录redmine，请教下这个是什么原因。

官网上的说明
To test this, create a Redmine user with a login that matches his LDAP account (normally, Redmine will advise you by looking up the LDAP data), select the newly created LDAP in the Authentication mode drop-down list (this field is visible on the account screen only if a LDAP is declared) and leave his password empty. Try to log in into Redmine using the LDAP username and password
但是在redmine上建了一个ldap存在的帐号，选择了之前创建的ldap认证名称，还是登录不了。 求解。

    The LDAP connection test only tests exactly that: a connection against the LDAP server, not an authentication or even if it can fetch the account information it needs.
    See if you have errors in your redmine logs (usually redmine_dir/log/production.log).
    Can you confirm any of the users you created can successfully log into the LDAP server, and that the user redmine connects to the LDAP can fetch all the needed user information (search for a user by uid and read all the other attributes)?

原因是Base DN多加了cn=admin。
