I'm not exactly sure what you meant by "I do not want to restrict the page to a few. Will this method not require me to explicitly add usernames of who can access". Well, there must be a list of users defined with password (password store) with any kind of authentication system. However, you can choose a format that allows you to more easily update who can have access (i.e. update the access list). You can also choose between an allow-by-default policy or a deny-by-default policy. That is if you don't want to have everybody authenticate, you can use an allow-by-default policy to define those explicitly require authentication, while the unstated ones can enter without authentication. This is all possible with easy Apache config.
The default password store is a text file. But Apache contains additional modules that allows you to put the authentication info in SQL database or DBM files that you can choose from. You can modify data stored in them from Perl.
I suggest you build yourself a simple test environment and see if that fits your use case because I'm not exactly sure what you meant.

dbmmanage
DBMMANAGE(1) dbmmanage DBMMANAGE(1)
NAME
dbmmanage - Manage user authentication files in DBM format
SYNOPSIS
dbmmanage [ encoding ] filename add|adduser|check|delete|update username [ encpasswd [ group[,group...] [ comment ] ] ]
dbmmanage filename view [ username ]
dbmmanage filename import
SUMMARY
dbmmanage is used to create and update the DBM format files used to store usernames and password for basic authentication of HTTP users via
mod_authn_dbm. Resources available from the Apache HTTP server can be restricted to just the users listed in the files created by dbmman-
age. This program can only be used when the usernames are stored in a DBM file. To use a flat-file database see htpasswd.
This manual page only lists the command line arguments. For details of the directives necessary to configure user authentication in httpd
see the httpd manual, which is part of the Apache distribution or can be found at http://httpd.apache.org/.
OPTIONS
filename
The filename of the DBM format file. Usually without the extension .db, .pag, or .dir.
username
The user for which the operations are performed. The username may not contain a colon (:).
encpasswd
This is the already encrypted password to use for the update and add commands. You may use a hyphen (-) if you want to get prompted
for the password, but fill in the fields afterwards. Additionally when using the update command, a period (.) keeps the original
password untouched.
group A group, which the user is member of. A groupname may not contain a colon (:). You may use a hyphen (-) if you don't want to assign
the user to a group, but fill in the comment field. Additionally when using the update command, a period (.) keeps the original
groups untouched.
comment
This is the place for your opaque comments about the user, like realname, mailaddress or such things. The server will ignore this
field.
Encodings
-d crypt encryption (default, except on Win32, Netware)
-m MD5 encryption (default on Win32, Netware)
-s SHA1 encryption
-p plaintext (not recommended)
Commands
add Adds an entry for username to filename using the encrypted password encpasswd. dbmmanage passwords.dat add rbowen foKntnEF3KSXA
adduser
Asks for a password and then adds an entry for username to filename. dbmmanage passwords.dat adduser krietz
check Asks for a password and then checks if username is in filename and if it's password matches the specified one. dbmmanage pass-
words.dat check rbowen
delete Deletes the username entry from filename. dbmmanage passwords.dat delete rbowen
import Reads username:password entries (one per line) from STDIN and adds them to filename. The passwords already have to be crypted.
update Same as the adduser command, except that it makes sure username already exists in filename. dbmmanage passwords.dat update rbowen
view Just displays the contents of the DBM file. If you specify a username, it displays the particular record only. dbmmanage pass-
words.dat view
BUGS
One should be aware that there are a number of different DBM file formats in existence, and with all likelihood, libraries for more than
one format may exist on your system. The three primary examples are SDBM, NDBM, the GNU project's GDBM, and Berkeley DB 2. Unfortunately,
all these libraries use different file formats, and you must make sure that the file format used by filename is the same format that dbm-
manage expects to see. dbmmanage currently has no way of determining what type of DBM file it is looking at. If used against the wrong for-
mat, will simply return nothing, or may create a different DBM file with a different name, or at worst, it may corrupt the DBM file if you
were attempting to write to it.
dbmmanage has a list of DBM format preferences, defined by the @AnyDBM::ISA array near the beginning of the program. Since we prefer the
Berkeley DB 2 file format, the order in which dbmmanage will look for system libraries is Berkeley DB 2, then NDBM, then GDBM and then
SDBM. The first library found will be the library dbmmanage will attempt to use for all DBM file transactions. This ordering is slightly
different than the standard @AnyDBM::ISA ordering in Perl, as well as the ordering used by the simple dbmopen() call in Perl, so if you use
any other utilities to manage your DBM files, they must also follow this preference ordering. Similar care must be taken if using programs
in other languages, like C, to access these files.
One can usually use the file program supplied with most Unix systems to see what format a DBM file is in.
