Mirek Malinowski commented on GUACAMOLE-1212:
---------------------------------------------
I agree it would be good to have an option to change it manually or be
addressed in some sort of agreed manner.
We end up doing is to comment out the check, compile it, and then FreeIPA
working as expected, been using it for over a year now. However, it's not
something I would recommend doing in bigger production environments, as the
checks are there for the reason and it's working in our limited use case.
> Support 2FA Directly in LDAP Extension

> Key: GUACAMOLE-1212
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1212
> Project: Guacamole
> Issue Type: Improvement
> Components: guacamole-auth-ldap
> Reporter: Brett Smith
> Priority: Minor
> Attachments: user-with-otp-trace-level.log
>
>
> I'm using FreeIPA in my environment. I have guacamole-auth-ldap enabled and
> configured and it works fine for users who do not have 2FA enabled. For our
> users with 2FA enabled, we are using TOTP tokens provided by FreeIPA.
> When investigating a tcpdump between guacamole and the LDAP server, I can see
> that guacamole passes the username and password to the LDAP server twice.
> This works fine for a traditional username and password, but for a
> 2FA-enabled user, the second authentication attempt returns failure since the
> TOTP is one-time use. 2FA login attempts result in the guacamole logs
> outputting "successfully authenticated" while the web UI shows "Invalid
> Login" in a red banner.
