Which of the following lines is valid in a configuration file in /etc/pam.d/?
Which of the following lines is valid in a configuration file in /etc/pam.d/?
In configuration files in /etc/pam.d/, the correct syntax typically follows the pattern of specifying the module interface (such as 'auth'), followed by the control flag (such as 'required'), and then the module name with options. The line 'auth required pam_unix.so try_first_pass nullok' adheres to this format correctly, where 'auth' specifies the module interface, 'required' is the control flag, and 'pam_unix.so' is the module name with the options 'try_first_pass' and 'nullok'.
A is correct! auth required pam_unix.so try_first_pass nullok
