Title: PPTP VPN + LDAP auth hangs DFL-260e. Help!
Post by: mortalius on March 05, 2013, 05:45:50 AM

Hi

I'm trying to configure DFL-260e for PPTP Server with LDAP auth with no result. DFL-260e hangs totally.

When using local user database for auth, it is all ok. User authenticated.
When i change in my UserAuthRule authentication source from localdb to LDAP, and then trying to connect via pptp to DFL, it freezes all network activity and becomes innacessible even with pings.

LDAP server is configured correctly, because i see ldap queries from DFL at server. Even if it is (may be) configured incorrect, it is not a reason for hanging.

Firmware Version: 2.40.01.08-17758 Mar 5 2012

I made it work only when switched off all CHAP auth protocols and leaved only PAP enabled.
DFL does not hangs anymore, but it also does not authenticates users via LDAP, because of incorrect bindRequest.

i've dumped ldap traffic and
in bindRequest dfl queries only uid! ignoring BaseObject attribute that is specified at my LDAP server settings (ou=VPN,dc=localdomain for me)

correct request: uid=username,ou=Group,dc=localdomain
DFL request: username

Any ideas what i do wronG?
