libsasl2 2.1.25-1 incompatible with latest openldap.

libsasl2 2.1.25-1 incompatible with latest openldap.

[Andrew Branson]

Hi,

After updating my cygwin yesterday, my openldap slapd failed to start, 
giving the following output:

$ /usr/sbin/slapd -d 1 -f /etc/openldap/slapd.conf
@(#) $OpenLDAP: slapd 2.3.43 (Mar 26 2012 13:27:31) $
 
vzell@vzell-de:/misc/src/release/openldap-2.3.43-3/build/servers/slapd
daemon_init: listen on ldap:///
daemon_init: 1 listeners to open...
ldap_url_parse_ext(ldap:///)
daemon: listener initialized ldap:///
daemon_init: 2 listeners opened
slapd init: initiated server.
slap_sasl_init: auxprop add plugin failed
slapd destroy: freeing system resources.
slapd stopped.
connections_destroy: nothing to destroy.

If I downgrade libsasl2 to version 2.1.23-1 then it works just fine. I 
couldn't find anyone else complaining about this, and it seems to be 
over a month since libsasl2 was updated. Am I doing something wrong? I 
replicated this problem on two different machines.

Thanks for any help,

Andrew

Apparently the problem is that SASL 2.1.25 changed the ABI in an
incompatible way without bumping the DLL version[1].

The easiest fix is to rebuild OpenLDAP against the updated SASL package.
It might also be possible for me to release a patched SASL package with
a bumped DLL version, preserving the previous DLL in the current
libsasl2 package, but I'd really prefer not to do that.
