[SSSD] SSSD and Sudo

[Marco Pizzoli]

Hi guys,
I had a look at this guide [1] but I'm not understanding the presented
use-case.

- I see that I have to add in /etc/nsswitch.conf the line "sudoers:   files
ldap".
   -> I'm telling sudo to check rules via ldap

- I have to add in sssd.conf the directive "ldap_netgroup_search_base =
cn=ng,cn=compat,dc=example,dc=com"
   -> I'm telling sssd where to search for netgroups

- I have to edit the file nslcd.conf and insert all ldap related stuff
necessary to access the ldap server.

This come my question: why do I have to split my conf between sssd.conf and
nslcd.conf ?
Can't I use directly sssd.conf and use it as sole tool/conf to access the
ldap server?
What am I missing?

Thanks a lot as usual
Marco
