[Freeipa-users] Application-specific password or OTP disable for specific external applications

We use FreeIPA for all our services. OTP is very useful on web but when we try to login on mobile we cannot get OTP password from Google Authenticator or FreeOTP mobile app. For example; if you want to login your mail on mobile you cannot enter your OTP password on the login screen. How can I disable OTP just for mail service. Anybody have any idea?
