Hi all,
I have a little problem. I am implementing an application that uses the OpenLDAP libraries. Until not too much time ago, linking with OpenSSL was sufficiently safe (on almost every Linux distros) and providing my own verification function through the SSL_CTX (by using the ldap_set_option(m_ldap, LDAP_OPT_SERVER_CERTIFICATE, _my_verify)) was easy.
Now, Linux distros started to use GnuTLS, NSS, and OpenSSL as the crypto API.
My question is: how do I develop an application that when deployed on different systems might need to use functions and data structures from different crypto-api (e.g., when I distribute the binaries of my app) ?
How can I retrieve that info *at runtime* (I'd like my binaries to be compatible) ?
At least, is there a function that allows me to know which crypto APIs are expected by libldap_r (so that I don't pass in the wrong data structure since it is a (void *)) ? Or at least, is there a way to set/get options so that I would know which API is in use ?
Thanks,
