OTP configuration

Manage the default values that IPA uses for OTP tokens.

EXAMPLES:

 Show basic OTP configuration:
   ipa otpconfig-show

 Show all OTP configuration options:
   ipa otpconfig-show --all

 Change maximum TOTP authentication window to 10 minutes:
   ipa otpconfig-mod --totp-auth-window=600

 Change maximum TOTP synchronization window to 12 hours:
   ipa otpconfig-mod --totp-sync-window=43200

 Change maximum HOTP authentication window to 5:
   ipa hotpconfig-mod --hotp-auth-window=5

 Change maximum HOTP synchronization window to 50:
   ipa hotpconfig-mod --hotp-sync-window=50
