There are changes in libldap and slapd-ldap related to TLS which might
not work correctly with GnuTLS.

So could you try to first link with OpenSSL? If that works it would mean
that the GnuTLS support needs some more work.

Ok that can be done, although I am pretty sure that it will work with OpenSSL since you have already tested a similar setup  on openSUSE.

The idea here is to first confirm with others the problem and then early identify the change set that triggers this before the announcement of the release

What worries me is that the exact config options and gnutls libs with the 2.4.47 source works as expected, thus we can not blame GNUTLS for that, despite any arguments one may have against GNUTLS.

BTW: During the last days Quanah and me investigated an issue with a
(now reverted) patch for libldap only occuring with dhcpd using libldap.
ldapsearch and many other LDAP clients were working just fine.

Ciao, Michael.
