[Samba] auth_audit on samba 4.15

[Daniel Berteaud]

Hi. 

I'm running a samba DC 4.14.10. I've configured logging so that 


    * Important messages about the service go to the Journal (level 1) 
    * auth_audit logs in /var/log/samba/auth.log at level 3 
    * auth_json_audit in /var/log/samba/json/auth.log at level 4 

This is done with 

logging = systemd at 1 file 
log level = auth_audit:3@/var/log/samba/auth.log auth_json_audit:4@/var/log/samba/json/auth.log 

After upgrading to samba 4.15.2, there's no authentication message sent anymore in those log files. Only authorization ones (if level >= 4). 
I checked the manual, but found no change regarding that. 

Is that expected ? Should I change anything in my conf to get authentication logged again, or is this a bug ? 

Regards, 
Daniel
