At work we host a number of [Debian](https://www.debian.org/) VMs. Most of them are integrated into the central active directory server using the [sssd](https://packages.debian.org/jessie/utils/sssd) package.

Quite unrelatedly my boss kept nagging me about incoming emails to root that looked like this

	Subject: *** SECURITY information for <host> ***

	<host> : Sep 29 05:45:42 : user : problem with defaults entries ; TTY=pts/0 ; PWD=/home/user ; 

I found the relationship between sssd and the eMails only after some heavy googling: the sssd package modifies `/etc/nsswitch.conf` and adds the sssd as the source for sudoers. 

Since we do not keep that info in active directory anyway the fix is easy - simply remove the sssd config for sudoers and enjoy a quiet life without security emails.
