Hi Quanah, Thanks for the response. Earlier, we tried to do a normal ldapsearch with a library compiled with HAVE_TLS, but what we got in the wireshark trace was ldap message over SSL without any encryption, instead of plain LDAP. So we thought it was not possible to get plain LDAP with library compiled with HAVE_TLS. As you said, we have missed out on something or probably misunderstood the APIs. I will try your suggestions. Thanks once again for your support. Regards, G Gokul On Thu, Mar 29, 2018 at 2:05 AM, Quanah Gibson-Mount <quanah(a)symas.com&gt; wrote:
