Hi,
I have a very strange issue with OpenLDAP 2.4 and the SQL backend. at_query fails although the exactly same query works fine with 2.3.
I posted some details on this question on SF: http://serverfault.com/questions/566902/openldap-sql-backend-failing There's also this Gist containing my config, the full error message, etc.: https://gist.github.com/ThiefMaster/b47613f79d6a3ed879df
Regards, Adrian
