I am trying to append to some lines within the nsswitch file to setup
sssd. I am trying this with the loop below, but I have never used backrefs
before. I am unsure if I am doing it correctly. I get an error about an
invalid group reference. I wonder if my regexp is wrong?
Code
- name: Update nsswitch.conf
replace:
path: /etc/nsswitch.conf
regexp: "{{item.regexp}}"
replace: "{{item.replace}}"
with_items:
- {regexp: '^passwd.*',
replace: '\1 sss'}
- {regexp: '^group.*',
replace: '\1 sss'}
notify: restart sssd
