How to use go to verify whether the plaintext password is the same as the salt md5 password?

Question

Python:

# generate password
ldap_salted_md5.hash("123456") 
# verify password
ldap_salted_md5.verify("123456","{SMD5}991RjK3DQCT+ri/yxQB613Yuxdg=")
# return true

shell:

# generate password
slappasswd -h {SMD5} -s "123456" 
# return {SMD5}ZmDHoIiZZG/weuCNkLj189sFoPM=
# verify password by python 
ldap_salted_md5.verify("123456","{SMD5}ZmDHoIiZZG/weuCNkLj189sFoPM=")
# return True

I want to use go to implement this step of ldap_salted_md5.verify

        saltPassword := strings.Replace(user.Password, "{SMD5}", "", -1)
        decodeSaltPassword, _ := base64.StdEncoding.DecodeString(saltPassword)
        checksum := decodeSaltPassword[0:16]
        salt := decodeSaltPassword[16:]

        md5Ctx := md5.New()
        md5Ctx.Write([]byte(bindSimplePw))
        md5Ctx.Write(salt)
        cipherStr := md5Ctx.Sum(nil)

        if !bytes.Equal(checksum, cipherStr) {

            return ldap.LDAPResultInvalidCredentials, nil
        }
