Posted on August 5, 2014 by admin Here is a quick way how to test LDAP and LDAPS connectivity with ldp.exe LDAP ===== 1. Run ldp.exe 2. Connection error 0x51 = ldap_connect(hldap null) > Connect, dc.mylab.local (Check SSL if you are testing ldaps) 3. Connection > error 0 = ldap_connect(hldap, null); Bind, (Administrator/Password/mylab.local), check "Bind with Credentials" 4. View > Tree, BaseDN (DC=mylab,DC=local) 5. Browse > Search Filter: (&(&(objectClass=User)(objectcategory=person))(objectClass=user)(samaccountname=JDoe)) Check ldap_opt_protocol_version, 3 your Policies If you can't connect with ldp.exe by using regular ldap you might have a policy set on your Domain Controller to specifically use LDAPS only. Double check the below and http://answers.microsoft.com/en-us/msoffice/forum/msoffice_outlook-mso_winother/cannot-connect-to-ldap-ssl-with-error-81-on-server/78999b14-c4fc-46ce-bddc-36307bd156ed these options should allow you to use regular ldap.

LDAPS ====== http://www.computertechblog.com/using-ldp-exe-to-test-ldap-and-ldaps-connectivity/ If you are getting the below error, chances are that you did not import the SSL certificate from the Domain Controller to the machine trying to do the LDAPS connection, follow the below steps to import the certificate. ld = ldap_sslinit("dc.mylab.local", 636, 1); Error 0 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3); Error 81 = ldap_connect(hLdap, NULL); Server error:

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}.
