asterisk users - Apr 2012 - How to disable CDR adaptative logging on asterisk 1.8 ?

Hi,

On a 1.8.10 system, I've got (with cdr show status) :

Call Detail Record (CDR) settings
----------------------------------
  Logging:                    Enabled
  Mode:                       Simple
  Log unanswered calls:       No

* Registered Backends
  -------------------
    csv
    cdr-custom
    Adaptive ODBC

The strange thing is that cdr.conf is almost empty (ie only a [csv]
section is uncommented and I've got no cdr_adaptative_odbc.conf file
(I renamed the one I add to  cdr_adaptative_odbc.conf.old).

How can I turn CDR Adaptive ODBC off ?

Regards
