loginResp.Message (dynamic remote login failure message)

Error message

loginResp.Message (dynamic remote login failure message)

What it means

When the remote pan-site login API returns success=false, the plugin wraps loginResp.Message (the remote's own failure text, trimmed) in a plain error. The message is dynamic and comes from the upstream server, so text varies (e.g. wrong password, captcha needed, account locked).

Solutions

1. Verify the configured pan-site username/password are correct
2. Log the trimmed loginResp.Message to see the exact upstream reason and act on it (captcha, lockout, etc.)
3. Re-test with a manual browser login to confirm the account is not locked or captcha-gated
4. Check whether the site changed its login API/response format and update LoginResponse parsing

Example fix

// before
if !loginResp.Success {
    return "", nil, errors.New(strings.TrimSpace(loginResp.Message))
}
// after
if !loginResp.Success {
    return "", nil, fmt.Errorf("pan login failed: %s", strings.TrimSpace(loginResp.Message))
}

// pre-validate credentials non-empty before calling login
if user == "" || pass == "" { return errors.New("missing pan credentials") }

cookie, links, err := login()
if err != nil {
    log.Printf("pan login failed: %v", err) // message is remote's own text
    return err
}

When it happens

Trigger: POSTing credentials to the pan-site login endpoint and receiving a JSON body with success=false; also triggered indirectly if json unmarshal of the response fails (separate wrapped error).

Common situations: Wrong username/password configured for the pan site; account requires captcha or SMS verification; account temporarily locked; site changed its response schema so Success is false by default.
