Fixing the dreaded “problem with defaults entries” in debian29.09.2018 by Dirk Olmes
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.
