slapd crashing with Mac OS X clients

[David Barker <D.R.Barker@exeter.ac.uk>]

Hello :-)

We have been happily authenticating various clients against our openldap 
install, including various Linux, Solaris & IRIX machines. Recently, a 
department has been experimenting with authenticating Mac OS X clients 
against our openldap servers, which has been causing slapd to fall over.

We were running 2.2.14, and have tried upgrading to 2.2.26 & 2.2.28, all 
of which still crash.

The mac seems to be able to list users, but it is the final step of 
actually authenticating that is causing slapd to fail. After some 
googling, it looks like we're experiencing the same problem as 
http://www.openldap.org/lists/openldap-software/200506/msg00278.html

Has anyone else come across this, or know how to fix it? :-)
