Thanks Chris but it didn't work.That article discusses about SSL and I am using TLS which is on port 389 so no URL issue.Here is a server side debug trace:

daemon: epoll: listen=7 active_threads=0 tvp=NULL TLS trace: SSL_accept:before/accept initialization daemon: epoll: listen=8 active_threads=0 tvp=NULL daemon: activity on 1 descriptor daemon: activity on: daemon: hangup on 14 tls_read: want=11 error=Connection reset by peer TLS trace: SSL_accept:error in SSLv2/v3 read client hello A daemon: epoll: listen=7 active_threads=0 tvp=NULL daemon: epoll: listen=8 active_threads=0 tvp=NULL daemon: activity on 1 descriptor daemon: activity on: TLS: can't accept. daemon: hangup on 14 daemon: epoll: listen=7 active_threads=0 tvp=NULL daemon: epoll: listen=8 active_threads=0 tvp=NULL daemon: activity on 1 descriptor daemon: activity on: daemon: hangup on 14 connection_read(14): TLS accept failure error=-1 id=5, closing

Any help or light on this wil lbe appreciated greatly.

Thanks,

Hi Christopher,

                   Thanks for your email.It seems that

without TLS , the search works first but next when I initiate a TLS session, the ldap api says "SERVER DOWN".I must mention that the bandwidth is very low in that VPN tunnel and there is only one route.

Now I used tcpdump to check the packets on port 389 , it seems that there are a lot of packets being exchanged.My guess is that because of the low b/w even if one packet gets dropped because of router overflow, the SSL handshake will be terminated.

What do you think?

Thanks,

Sankhadip

  You might try putting the LDAP server's name and IP

address in the hosts file of the client.
