This seems to me to be the very same as bug 1590660. The bug is internal-only and not within my jurisdiction any more, however it seems the issue is the dhcpd does not initialize libldap's TLS context properly. I'm changing the component to 'dhcp' so as to be handled on their side. *** Bug 1590660 has been marked as a duplicate of this bug. *** The problem came from bind dst library [1]. it effectively breaks random numbers generation for any client but BIND [2] so SSL_connect fails with -1. As a workaround we can call ldap_set_option(NEWCTX) from within dhcp code before isc_lib_register() to use default implementation but I'm not sure if it'll not break anything else. At first glance it should not.
