Ansible pamd: module failure - ansible

Question

i have this playbook as a part of a role that do some changes in pam modules :
---
- name: "{{ BANNER}} - SET MODE"
copy:
remote_src: True
src: "{{ LOGIN_DEF }}"
dest: "{{ LOGIN_DEF_BCK }}_RH7-021_{{ CK_ORA }}"
replace:
path: "{{ LOGIN_DEF }}"
regexp: '{{ item.src }}'
replace: '{{ item.dst }}'
with_items:
- { src: '(.*FAIL_DELAY.*)', dst: '#\1' }
lineinfile:
path: "{{ LOGIN_DEF }}"
line: 'FAIL_DELAY 10'
replace:
path: "{{ PASSWORDAUTH }}"
regexp: '{{ item.src }}'
replace: '{{ item.dst }}'
with_items:
- { src: '^auth .* pam_faildelay.so', dst: '' }
pamd:
name: password-auth
type: auth
control: sufficient
module_path: 'pam_unix.so'
new_type: auth
new_control: optional
new_module_path: 'pam_faildelay.so'
module_arguments:
state: after
replace:
path: "{{ SYSTEMAUTH }}"
regexp: '{{ item.src }}'
replace: '{{ item.dst }}'
with_items:
- { src: '^auth .* pam_faildelay.so', dst: '' }
pamd:
name: system-auth
type: auth
control: sufficient
module_path: 'pam_unix.so'
new_type: auth
new_control: optional
new_module_path: 'pam_faildelay.so'
module_arguments:
state: after
debug: msg="{{ MSG_SET }}"
When i run i have this error :
TASK [RH7-021 : pamd] ***********************************************************************************************************************************************

to retry, use: --limit #/home/PG005856/HARDENING/main.retry
I can't figure it out what's wrong morover i used the same method on other playbook at it worked fine.
The control node has this ansible version :
ansible 2.7.6
config file = /home/PG005856/HARDENING/ansible.cfg
configured module search path = [u'/home/PG005856/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /ansible/lib/python2.7/site-packages/ansible
executable location = /ansible/bin/ansible
python version = 2.7.5 (default, Feb 20 2018, 09:19:12) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]
Thr target server is :
Linux rh7-test-ansible 3.10.0-693.17.1.el7.x86_64 #1 SMP Sun Jan 14 10:36:03 EST 2018 x86_64 x86_64 x86_64 GNU/Linux
cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.4 (Maipo)
I have read that was a bug but i could imagined that with ansible version 2.7 was resolved.
I don't know what to do i could archieve the same result with some lines of sed with shell module but i'd like to use the pamd: module.
