Synopsis 

Edit PAM service’s type, control, module path and module arguments.
In order for a PAM rule to be modified, the type, control and module_path must match an existing rule. See man(5) pam.d for details.

Parameters 

Parameter	Comments
backup boolean	Create a backup file including the timestamp information so you can get the original file back if you somehow clobbered it incorrectly. Choices: no ← (default) yes
control string / required	The control of the PAM rule being modified. This may be a complicated control with brackets. If this is the case, be sure to put “[bracketed controls]” in quotes. The `type`, `control` and `module_path` all must match a rule to be modified.
module_arguments list / elements=string	When state is `updated`, the module_arguments will replace existing module_arguments. When state is `args_absent` args matching those listed in module_arguments will be removed. When state is `args_present` any args listed in module_arguments are added if missing from the existing rule. Furthermore, if the module argument takes a value denoted by `=`, the value will be changed to that specified in module_arguments.
module_path string / required	The module path of the PAM rule being modified. The `type`, `control` and `module_path` all must match a rule to be modified.
name string / required	The name generally refers to the PAM service file to change, for example system-auth.
new_control string	The new control to assign to the new rule.
new_module_path string	The new module path to be assigned to the new rule.
new_type string	The new type to assign to the new rule. Choices: account -account auth -auth password -password session -session
path path	This is the path to the PAM service files. Default: “/etc/pam.d”
state string	The default of `updated` will modify an existing rule if type, control and module_path all match an existing rule. With `before`, the new rule will be inserted before a rule matching type, control and module_path. Similarly, with `after`, the new rule will be inserted after an existing rulematching type, control and module_path. With either `before` or `after` new_type, new_control, and new_module_path must all be specified. If state is `args_absent` or `args_present`, new_type, new_control, and new_module_path will be ignored. State `absent` will remove the rule. The ‘absent’ state was added in Ansible 2.4. Choices: absent before after args_absent args_present updated ← (default)
type string / required	The type of the PAM rule being modified. The `type`, `control` and `module_path` all must match a rule to be modified. Choices: account -account auth -auth password -password session -session
