I believe it's been Debian policy for years to use GnuTLS over
OpenSSL if the application has support for it.
The OpenSSL licence issue is so annoying.

Hmm, this got me digging... it didn't help that we hit an ldap
problem today (which is a weird one, caused by a group getting too
big - it may be related to this, I'm still digging).
It turns out Debian is also linked against gnutls.
However, having run with ldap code for ages, apart from today,
things have generally been solid.
Not saying libldap linked against gnutls is perfect, but given our
experience and the queries on this list, it seems to be more
stable than when linked against nss.
If I get time I'll compile libldap against openssl and see if that
fixes the issue we've seen today. In which case it'll be one case
against gnutls as well.
