  script_tag(name:"summary", value:"Attempts to enumerate valid usernames on web servers running with the mod_userdir module or similar
enabled.

The Apache mod_userdir module allows user-specific directories to be accessed using the
http://example.com/~user/ syntax.  This script makes http requests in order to discover valid user-
specific directories and infer valid usernames.  By default, the script will use Nmap's
'nselib/data/usernames.lst'.  An HTTP response status of 200 or 403 means the username is
likely a valid one and the username will be output in the script results along with the status code
(in parentheses).

This script makes an attempt to avoid false positives by requesting a directory which is unlikely to
exist.  If the server responds with 200 or 403 then the script will not continue testing it.

SYNTAX:

userdir.users:  The filename of a username list.

limit:  The maximum number of users to check.

http-max-cache-size:  The maximum memory size (in bytes) of the cache.

http.pipeline:  If set, it represents the number of HTTP requests that'll be
pipelined (ie, sent in a single request). This can be set low to make
debugging easier, or it can be set high to test how a server reacts (its
chosen max is ignored).");
