[jira] [Created] (GUACAMOLE-1212) Cannot authenticate with OTP-enabled LDAP user

Brett Smith created GUACAMOLE-1212:
--------------------------------------

             Summary: Cannot authenticate with OTP-enabled LDAP user
                 Key: GUACAMOLE-1212
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1212
             Project: Guacamole
          Issue Type: Bug
          Components: guacamole-auth-ldap
    Affects Versions: 1.2.0
            Reporter: Brett Smith


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.
