when 2FA enabled, with 2 factor prompt asking doesn't work

[seojeong kim]

on server side,   ipauserauthtype set as password + otp. 
[root@xxxxxx /]# ipa user-show ereen-test --raw | grep ipauserauthtype
  ipauserauthtype: password
  ipauserauthtype: otp

And I added new configuration  in   /etc/ssh/sshd_config  on my host which is ipa  client is installed.
    GSSAPIAuthentication yes

And /etc/sssd/sssd.conf 
 [prompting/password/sshd]
 password_prompt = password :
 [prompting/2fa/sshd]
  first_prompt = first pwd :
  second_prompt = second otp :

But all the time, when I try ssh login with ereen-test,    the prompt asks        "password :" 
I expect 2 factor asking  as I configured like below 
    first_prompt : 
    second_prompt :

Is there other configuration should I set more ?
