I've installed the root certificate into Trusted Root Authorities (Computer Local) and I've created a certificate here for the server in question and imported that into Personal (Computer Local). I used OpenSSL to tie the private key to the certificate. However, this setup doesn't seem to be working when I try and get a 3rd party app called OpenFire (the server its running on also has the StartCom root certificate installed) to connect. I've been looking at the Microsoft article http://support.microsoft.com/kb/321051 but elements like Enhanced Key usage mean nothing to mean, and I'm rather hoping someone has tried to setup AD w/ SSL before and might be able to give me a pointer.Attempting a connection using ldp.exe to the PDC on port 636 using SSL (with the relevant root certificate in my computer's Trusted Local Root Authority folder) I get the following:ld = ldap_sslinit("{server_name}", 636, 1);Error = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, LDAP_VERSION3);Error = ldap_connect(hLdap, NULL);Server error: Error : Fail to connect to {server_name}.

I want to turn on LDAPS on this AD, so that I could access the AD via secure connection. I have followed the following guide: http://social.technet.microsoft.com/wiki/contents/articles/2980.ldap-over-ssl-ldaps-certificate.aspx I have done everything in "Publishing a Certificate that Supports Server Authentication" and "Exporting the LDAPS Certificate and Importing for use with AD DS". When I try to netstat, I can see that port 636 is open, but its IP address is 0.0.0.0, which supposedly means that it cannot be error 81 ldap_set_option accessed from outside. The plain LDAP does work and I can both connect to it and see it in netstat as open both for 0.0.0.0 and my domain controller's IP address, but I cannot access the domain controller via LDAPS. What is the problem? Have I missed some step in this guide? What do I need to do extra? I have tested LDAP and LDAPS connection with Active Directory Administration Tool. This is the output I get from LDP.EXE: ld = ldap_sslinit("10.165.0.10", 636, 1); Error 81 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3); Error 81 = ldap_connect(hLdap, NULL); Server error:

Join Now Hi All, We're currently unable to connect to LDAPS port 636 using ldp.exe. I get the following error message when I attempt to connect: "ld = ldap_sslinit("srv-vdc1", 636, 1); Error 81 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3); Error 81 = ldap_connect(hLdap, NULL); Server error: Error <0x51>: Fail to connect to srv-vdc1." This also instantly throws up an event ID: 36869 "The SSL server credential's certificate does not have a private key information property attached to it. This most often occurs when a certificate is backed up incorrectly and then later restored. This message can also indicate a certificate enrollment failure." All servers mentioned below are 2012 R2 with latest updates. The server we're trying to configure is a Domain Controller (DC1), weirdly our other DC (DC2) works perfectly, with an identical certificate (apart from the 'issued to' of-course.) I am requesting the certificate from our CA server, as opposed to importing it manually. The certificate in question, is in the DC1 local computer > personal store. The cert has both Client and Server authentication, is within the valid from-to dates, and also states that "You have a private key that corresponds to this certificate". have tried the 'certutil -repairstore my "serial number"' command with no success. I can confirm that I can successfully connect to standard LDAP 389 with DC1 Any suggestions will be greatly appreciated. Thanks in advance, DG Reply Subscribe View Be
