LDAP authentication and MS SQL Server logging

I'd like ldap authentication for users and ODBC MSSQL Server for logging.
LDAP authentication is working fine but I get no logging in my SQL "EJABBERD" database.
DSN is OK (tested, no error)
Here is my ejabberd.cfg file (part of).
Thank you in advance for your help.
