Requesting information about libraries/ldap_r
by jjrobert＠lexmark.com 01 Feb '23

01 Feb '23

We are upgrading our stack from using openldap 2.4.57 to 2.5.12 and one of our dependencies is missing lldap_r. I searched and only really found this, which gives me some idea of its purpose: https://marc.info/?l=openldap-devel&m=95218635611825 Is it simply gone now, or does it exist as a separate library? Is there any guidance on what to do if you were using it previously? Thanks, -Jeff

How to retrieve invalid CA certificate error upon ldap over TLS connection using openldap PAI
by tishamol＠gmail.com 27 Jan '23

27 Jan '23

Hi, How can i get an error specific to invalid CA certificate for an ldaps connection(LDAP over TLS)? Our flow is like this 1:ldap_initialize() 2:ldap_sasl_bind_s() But even if i import an invalid CA certificate on ldap client to verify the server certificate , i don't get any error specific to TLS handshake fail. ldap_sasl_bind_s()() always return -1. Can you suggest someway to fetch this error from openldap? Thanks, Smitha
