Golang与LDAP通信

Question

我正在尝试使用golang连接和验证用户ldap.

我正在使用带有以下示例代码的go-ldap-client:

package main

import (
    "log"
    "github.com/jtblin/go-ldap-client"
)

func main() {
    client := &ldap.LDAPClient{
        Base:         "dc=example,dc=com",
        Host:         "ldap.example.com",
        Port:         389,
        UseSSL:       false,
        BindDN:       "uid=readonlysuer,ou=People,dc=example,dc=com",
        BindPassword: "readonlypassword",
        UserFilter:   "(uid=%s)",
        GroupFilter: "(memberUid=%s)",
        Attributes:   []string{"givenName", "sn", "mail", "uid"},
    }
    # It is the responsibility of the caller to close the connection
    defer client.Close()

    ok, user, err := client.Authenticate("username", "password")
    if err != nil {
        log.Fatalf("Error authenticating user %s: %+v", "username", err)
    }
    if !ok {
        log.Fatalf("Authenticating failed for user %s", "username")
    }
    log.Printf("User: %+v", user)

    groups, err := client.GetGroupsOfUser("username")
    if err != nil {
        log.Fatalf("Error getting groups for user %s: %+v", "username", err)
    }
    log.Printf("Groups: %+v", groups) 
}

已安装对gopkg.in/ldap.v2的依赖性.

该问题是,我收到以下错误:

2016/01/15 17:34:55 Error authenticating user username: LDAP Result Code 2 "Protocol Error": ldap: cannot StartTLS (unsupported extended operation)
exit status 1

有关此错误的任何提示？

好的,让我们尝试使用身份验证github.com/go-ldap/ldap.首先,你需要创建一个*ldap.Conn.如果您的LDAP服务器支持,我建议使用TLS:

// TLS, for testing purposes disable certificate verification, check https://golang.org/pkg/crypto/tls/#Config for further information.
tlsConfig := &tls.Config{InsecureSkipVerify: true}
l, err := ldap.DialTLS("tcp", "ldap.example.com:636", tlsConfig)

// No TLS, not recommended
l, err := ldap.Dial("tcp", "ldap.example.com:389")

现在您应该与LDAP服务器建立活动连接.使用此连接,您必须执行绑定:

err := l.Bind("user@test.com", "password")
if err != nil {
    // error in ldap bind
    log.Println(err)
}
// successful bind
