We get almost daily emails with the message:
Subject: *** SECURITY information for tools-sgeexec-0939.tools.eqiad.wmflabs *** tools-sgeexec-0939.tools.eqiad.wmflabs : Jun 2 01:52:08 : prometheus : problem with defaults entries ; TTY=unknown ; PWD=/var/lib/prometheus ; USER=root ;
That is caused by failing to retrieve the sudo directives from the sss module:
root@tools-sgeexec-0939:~# grep sudoers /etc/nsswitch.conf sudoers: files sss
We should investigate and/or keep track of these errors (might be periodical LDAP issues)
