Can you step through it with something like gdb?  Looking at the CHANGES 
file, I don't see anything obvious, unless you disabled IPv6 during 
compilation and its trying to use an IPv6 address (ITS#8754) or 
AI_ADDRCONFIG does odd things on your system (ITS#7326).

Thanks for the confirmation.

Any idea how I could find out what's going wrong? dhcpd seems to
dynamically link libldap 2.4.48 but fails to properly use it.

Ciao, Michael.

There should be no ABI changes.

For my understanding: Does 2.4.48 require applications linked to libldap
to be rebuilt or is it ABI compatible?

In most of my tests I can use 2.4.48 as binary drop-in replacement for
2.4.47. For this to work I've patched away the "releng" suffix. [1]

But dhcpd (using LDAP as backend) refuses to correctly start when using
libldap 2.4.48. It says "Can't contact LDAP server" although the server
is reachable. Looking at its strace output and slapd syslog dhcpd does
not even try connecting to slapd. After reinstalling libldap 2.4.47
everything works again.

It's not a big deal because in this packaged environment everything gets
rebuilt anyway if OpenLDAP upgrade is pushed. But I want to make sure I
fully understand everything and there's no issue left e.g. by
introducing openldap.h.

Ciao, Michael.
