Re: OpenLDAP crashing on search...

I have just done a fresh install of SuSE Linux 7.2 Pro on a spare system 
copied my LDAP data and tried the search, and it didn't crash slapd.

I then did an online update and tried the search again - and it causes the server to crash.

It appears as if the change between the different RPM's for OpenLDAP as 
distributed by SuSE introduces this error.
