TACACS+ 配置：如何接收 priv-lvl 值？

我需要配置 TACACS+ 服务器以了解给定用户是否经过身份验证*以及他的权限级别是多少。作为客户端，我使用 tactest (tacacs.net) 和 TACACS+ 客户端 Java 库 (AXL)。

我尝试过这个：

user = admin {
    name = “Admin User”
    login = cleartext admin
    service = exec {
      priv-lvl = 10
  }
}

并且可以作为管理员进行身份验证，但无法获取他的特权级别。

以下是 tactest 的输出：

C:\Program Files (x86)\TACACS.net>tactest -s x.x.x.x -k testing123 -u admin -p admin -author -service exec
Trying to open connection to x.x.x.x:49

有没有办法获取该属性值？

*我知道这不仅是身份验证，也是一种授权

我终于找到了解决方案。我只需要将服务名称更改为其他名称：

user = admin {
    name = “Admin User”
    login = cleartext admin
    service = myservice {
      priv-lvl = 10
  }
}

然后我就能在客户端获得 AV 对了：

Received Header:
MajorVersion=12
MinorVersion=0
Type=Authorization
SeqNum=2
IsEncrypted=True
IsSingleConnect=False
SessionID=952769599
DataLength=18

Received Body:
 Authorization Status=PassAdd
User=
Port=
Args: priv-lvl=10
