0756ce7d53 Properly handle LDAP socket closures in ipa-otpd
In at least one case, when an LDAP socket closes, a read event is fired
rather than an error event. Without this patch, ipa-otpd silently
ignores this event and enters a state where all bind auths fail.

To remedy this problem, we pass error events along the same path as read
events. Should the actual read fail, we exit.

168a6c7d47 Ensure that ipa-otpd bind auths validate an OTP
Before this patch, if the user was configured for either OTP or password
it was possible to do a 1FA authentication through ipa-otpd. Because this
correctly respected the configuration, it is not a security error.

However, once we begin to insert authentication indicators into the
Kerberos tickets, we cannot allow 1FA authentications through this
code path. Otherwise the ticket would contain a 2FA indicator when
only 1FA was actually performed.

To solve this problem, we have ipa-otpd send a critical control during
the bind operation which informs the LDAP server that it *MUST* validate
an OTP token for authentication to be successful. Next, we implement
support for this control in the ipa-pwd-extop plugin. The end result is
that the bind operation will always fail if the control is present and
no OTP is validated.

203754691c Add the krb5/FreeIPA RADIUS companion daemon
This daemon listens for RADIUS packets on a well known
UNIX domain socket. When a packet is received, it queries
LDAP to see if the user is configured for RADIUS authentication.
If so, then the packet is forwarded to the 3rd party RADIUS server.
Otherwise, a bind is attempted against the LDAP server.
