The PAM configuration file consists of entries with the following syntax:
service_name module_type control_flag module_path module_options |
service_name |
Is the name of the service (for example, ftp, login, telnet). |
module_type |
Is the module type for the service. For more information see PAM Module Types. |
control_flag |
Determines the continuation or failure behavior for the module. |
module_path |
Specifies the path to the library object that implements the service. |
module_options |
Specifies the options that are passed to the service modules. |
You can add comments to the pam.conf file by starting the line with a # (pound sign). Use white spaces or tabs to delimit the fields.
An entry in the PAM configuration file is ignored if one of the following conditions exist: the line has less than four fields, an invalid value is given for module_type or control_flag, or the named module does not exist.
