Esteemed Collegues, I have created a Playbook to replcae the Entry in a file using a `lineinfile` module, while i tried running it run and replace in entry on the one host while not on the another host, i don’t understand why? as it doesn’t report any error even on the debug mode. Do i need to have some another `regex` pattern.

`You need to account for white space. Try:`  
` `

```auto
regexp: '^passwd:.*files ldap'

```
