es连接ldap报错

看你的报错是连接到了ldap。
我的报错信息是这个，有遇到过吗？
[WARN ][o.e.x.s.a.AuthenticationService] [elk-node-1] Authentication to realm ldap1 failed - authenticate failed (Caused by LDAPException(resultCode=49 (invalid credentials), errorMessage='invalid credentials', ldapSDKVersion=4.0.8, revision=28812))

我也碰到了连接ldap时，报凭据无效的错误。。。

各位大佬，问题解决了没有？我也碰到elasticsearch接入ldap的问题，版本是7.7及以上的。如下：
