After I managed to connect to the LDAP server with gnutls-cli (with a PKCS#11
URI containing a pinfile attribute) I tried to set those PKCS#11 URIs to the
ldaprc settings TLS_KEY and TLS_CERT. But these settings are handled as PEM
encoded file (see function tlsg_ctx_init in tls_g.c) and a connection
initialization fails trying to read the PKCS#11 URI from the local file system.
So currently there seems to be no way to configure the OpenLDAP client to look
up the pkcs#11 store for the client key as well as the client certificate to
establish a client authenticated TLS connection.
If PKCS#11 support for smartcard/HSM is needed I'd try to use libnss
(--with-tls=moznss). Never tried that myself though.
