[Samba] check_account: Failed to convert SID messages in a log

[Christian Naumer]

Hi you all,
since now we have upgrade all our server to 4.15.x we are also getting 
flooded with these messages.
Are there any plans to use a higher loglevel for these? Or is there a 
workaround?


Regards


Christian
