In the cipher list "my existing config SECURE256 became 256SECURE", ie the
setting:
# GnuTLS specific
#ldap-tls-crlfile "/etc/ssl/crl/ssl-cert-local-ca.crl";
ldap-tls-cert "/root/.pki/dhcpd.pem";
ldap-tls-key "/root/.pki/dhcpd.key";
ldap-tls-ciphers "TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!3DES:@STRENGTH";
# GnuTLS specific
#ldap-tls-ciphers "256SECURE";
There was also a comment in that bug about openssl specific calls which
fail when dhcpd is linked against libnss (the gnutls library).
As mentioned by others in this email thread it looks like dhcpd needs to
be smarter about which functions are available in the shared library. So
that's a dhcpd bug, but not a straight forward one to fix.
