Publish LDAP Protocol through ISA 2006

Hi All,

we have a3-legged ISA 2k6 server.

We have an LDAP server on the internal network.
My problems is we use an external site to host web portal which needs to connect to our LDAP server through ISA. However, all LDAP connection are Denied Connection by the default rule.

We are only expecting traffic on 389, so the protocl is published as standard through the wizzard.

I would be obliged if someone could shed some light on this problem for me. I've attached a log extract for further reference.

Many thanks,
Adam.

Try something for me.
Ceate a new protocol called ldap-inbound to use tcp, port 389 - 389, inbound. Edit your non-web server publishing rule and use the new user-defined protocol and retest. The default ldap protocol is outbound traffic.

create a rule that allow LDAP from the desired server without any ports specified, and then tune to allow only the required port.

It is only LDAP port 389 that is used, the log has all traffic from the single client IP.

So I've published the LDAP protocol on the ISA server and log files is the result.
Denied Connection by Default Rule.
