Windows ldaps openssl

By default, Windows Active Directory servers are unsecured. All LDAP messages are unencrypted and sent in clear text. This restricts what developers can and can't do via LDAP. Here are the steps I used to secure my Active Directory server using a self signed certificate. If you are creating your own certificate, you need to first create a Certificate Authority CA.

Fortunately, tools like OpenSSL makes this easy. PSK identity: None. PSK identity hint: None. SRP username: None. Start Time: Timeout : sec. Verify return code: 21 unable to verify the first certificate.

We liked using ldapsearch for performing this. The whole process , a few lines, but this is the gist of it:. The first line fetches the cert from server and the second line parses the cert and allows transforming it into different formats, for example:.

The application is retrieving the VeriSignA certificate when searching for certificates on port I'm pretty sure that this is an application issue, but want to ensure that it's not a certificate problem.

My question is: is there a way to see what certificate is being used to allow port SSL traffic? But when a certificate is actually loaded, you can only verify it by using LDP, Connect to port with the SSL checkbox enabled and you will see if the connection is really established.

But not the certificate hash. The only way how I was able to see the certificate is using Network Monitor and lookup the contents of the on-wire transmission. In order to support LDAPS authentication from virtually any client, you will need to have a certificate that has both client authentication and server authentication.

Typically, you do not have more than one certificate on the DCs, so I have not looked into determining the exact one it uses. New LDP connections that I create will show up here as well, obviously. I don't see any LDAP interface errors at all in my Directory Services event log, which isn't surprising as I don't think there is anything wrong. This is useful because the old certificates on the server were bit, and the new ones are bit. So this shows that the LDP connection is using the new certificate.
