Hi,
We are currently evaluating keycloak as a possible authentication mechanism
deployed to our facility.
We use kerberos for user authentication with FreeIPA and configured sssd
for user federation in keycloak (follow the official document both from
keycloak and freeipa.org)
One of the requirement we desire is to enable kerboros password for SSH
login and enabled 'otp' for HTTP based applications.
To do so,
1. We enabled both user-auth-types for the user:
- password
- password + otp
2. Created HBAC rules in IPA, allowing keycloak server access for following
services: (I purposely did not enable 'otp' at this point as I want to
verify both 'password' and 'otp' shall work)
- keycloak
- sshd
3. Confimred sshd worked with both 'password' and 'otp' types via PAM/SSSD,
then I went ahead and accessed URL that is protected by keycloak,
'password' works but 'otp' won't, the following ERRORs were seen in
keycloak's server.log:

------------------
Interesting thing is keycloak handles OTP just fine if I have
'password+otp' only checked on, then we won't be able to log onto the
machines via SSH using password, that defeats our purposes.
I tested different version of JAVA and the latest keycloak (4.8.3) version
(on REHL 7), all got the same results.
I'm wondering if this is more likely a bug or I missed something.
I'd appreciate if someone can advice what the approach is.
Thank you very much.
