Attempt to bindRequest multiple times in the same LDAP connection. Disconnecting

[vlaf]

I’m facing the following issue using nginx ldap module and pointing it to the duoproxy ldap service.

Authentication always times out with ldap server unreachable on nginx with the duoproxy log showing:

Attempt to bindRequest multiple times in the same LDAP connection. Disconnecting.

This occurs after a succesful primary bind, secondary bind and successful duo push/authentication… Is there anyway to allow multiple binds for the same connection?

I can replicate this behavior using ldp.exe on Windows [connect (success), bind 1(success), bind 2(success, bind 3 (failure)]

Hi vlaf,

The Duo Authentication Proxy does not currently support multiple bindRequests in the same connection. You can contact Duo Support to open a feature request for this, so you may be notified directly if we add this to the proxy in a future release.

Thanks for trying Duo!

I believe you should be able to do allow_unlimited_binds = true

allow_unlimited_binds

Correct, we added that option in December 2017.
