Strange behavior when running go-ldap

wiltonsr opened this issue · comments

The following program sample.go triggers an unexpected result

package main

import (
	"fmt"

	"github.com/go-ldap/ldap/v3"
)

func main() {
	conn, err := ldap.Dial("tcp", fmt.Sprintf("%s:%d", "ldap.forumsys.com", 389))
	fmt.Println(err)
	defer conn.Close()
	conn.Debug = true
	conn.Bind("uid=tesla,dc=example,dc=com", "password")
}

Expected result
