Hi joe,
The CRL location is *not* available from the outside. And since neither
adfind, ldp or Outlook Express seemed to care, I am guessing that not many
(any?) tools require it. Kinda makes ya wonder why you would have it if it's
not used. Sorta like not using the book of bad credit card numbers when
someone handed you a credit card! (maybe some of you are old enough to
remember this safeguard before there were computers everywhere! LOL!).

Cool, is the CRL available from the outside at all? I am really curious if that
is truly needed from the client when using LDAPS, it doesn't seem to be needed
but my testing has been far from perfect in that regard.

Thanks to all who responded! The problem was solved by installing our local
root CA cert on the "outside" computer since we are "rolling our own" and not
using one of the well known CAs (Trusted Root Certification Authorities).

Hi Robert,
Yes, the command is *exactly* the same. We are thinking that our CRL
location is not available outside of the firewall. We generate our own
certificates; we don't use a "well known" provider.

Hey Mike,
When you say "It works fine behind our firewall", are you meaning that the
*exact same* command line works and you get the object returned?
I tried using adfind to connect to my test DC using port 636 and got the exact
same error...but I don't have a cert installed on my DC so I'd expect mine not
to work.

Subject: [ActiveDir] Secure LDAP queries from the outside
Hi,
We are trying to set up secure LDAP queries from the outside to AD for
pulling email addresses but are running into an issue. Port 636 has been
opened up to our DCs but we get a 0x51 error like the one shown below in this
example of using "adfind":
adfind -h dc1.abc.com:636 -u [EMAIL PROTECTED] -up * -default -nodn -f
sn=thommes extensionAttribute2
AdFind V01.26.00cpp Joe Richards ([EMAIL PROTECTED]) February 2005
LDAP_BIND: [rhino221.anl.gov] Error 0x51 (81) - Server Down
Terminating program.
(extensionAttribute2 is used for email address)
Portqry shows that the DC is listening on port 636. Using "ldp", the bind
operation seems to want to default to port 389 (which is not open).
It works fine behind our firewall. Is there some other port that needs to be
open (besides 389)? Or maybe some security feature (we are running w2k3/sp1 on
our DCs) that is getting in the way? Any help is appreciated!
TIA,
Mike Thommes
