This means that once + a pattern is matched in some file no further files are parsed. + If a config file is explicitly specified with the <option>accessfile</option> + option the files in the above directory are not parsed. + </para> + <para> + If Linux PAM is compiled with audit support the module will report + when it denies access based on origin (host, tty, etc.). + </para> + </refsect1> + + <refsect1 id="pam_access-options"> + <title>OPTIONS</title> + <variablelist> + + <varlistentry> + <term> + <option>accessfile=<replaceable>/path/to/access.conf</replaceable></option> + </term> + <listitem> + <para> + Indicate an alternative <filename>access.conf</filename> + style configuration file to override the default.

For example: + <emphasis remap='B'>fieldsep=|</emphasis> will cause the + default `:' character to be treated as part of a field value + and `|' becomes the field separator.
