按场景配置sssd.conf，重启sssd服务失败

一、环境信息
**内核信息：**
6.4.0-3.0.0.11.oe2309.aarch64
**缺陷归属组件：**
sssd
**缺陷归属的版本：**
sssd-2.9.1-2

**二、问题复现步骤
1、给/etc/sssd/sssd.conf做如下配置：
[sssd]
services = nss, pam
domains = shadowutils

[nss]

[pam]

[domain/shadowutils]
id_provider = files

auth_provider = proxy
proxy_pam_target = sssd-shadowutils

proxy_fast_alias = True

2. systemctl restart sssd启动服务
3. systemctl status sssd查看服务
三、实际结果
sssd服务启动失败

旧版本社区未对配置文件的正确性进行检查，社区正常演进，最新版本新增了检查判断：
