Re: Enable LDAP over SSL



OK.... that gives me more to chew on.
I see this in the system log.
Event Type: Warning
Event Source: Schannel
Event Category: None
Event ID: 36872
Date: 8/20/2007
Time: 3:46:18 PM
User: N/A
Computer:
Description:
No suitable default server credential exists on this system. This will
prevent server applications that expect to make use of the system default
credentials from accepting SSL connections. An example of such an application
is the directory server. Applications that manage their own credentials, such
as the internet information server, are not affected by this.

and this in the directory service log

Event Type: Information
Event Source: NTDS LDAP
Event Category: LDAP Interface
Event ID: 1220
Date: 8/16/2007
Time: 3:51:10 PM
User: N/A
Computer:
Description:
LDAP over Secure Sockets Layer (SSL) will be unavailable at this time
because the server was unable to obtain a certificate.

You will need the full cert chain on the DCs, but you should not need the
full chain on the client as AD should provide the whole chain to the client
during the SSL negotiation.

There are usually useful error messages in the system event log from
schannel and sometimes errors from LDAP in the Directory Service log when
there are SSL configuration problems.

I have seen this fail when the CA cert from the third party isn't properly
imported into both the client and all dc's cert stores.

I followed the instructions in KB321051 to install a certificate.
I got to the section "Verifying an LDAPS connection" and cannot connect
to
636 or 3269. Error <0x51>: Fail to connect
389 works fine.
I don't see an _ldap entry in DNS.
The domain controller I'm working with has no IIS and our network has no
CA
