NAME

dbmmanage - Create and update user authentication files in DBM format

SYNOPSIS

dbmmanage filename [ command ] [ username [ encpasswd ] ]

DESCRIPTION

dbmmanage is used to create and update the DBM format files used to store usernames and password for basic authentication of HTTP users. Resources available from the httpd Apache web server can be restricted to just the users listed in the files created by dbmmanage. 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 Apache 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.
command
This selects the operation to perform:
add
Adds an entry for username to filename using the encrypted password encpassword.
adduser
Asks for a password and then adds an entry for username to filename .
check
Asks for a password and then checks if username is in filename and if it's password matches the specified one.
delete
Deletes the username entry from filename.
import
Reads username:password entries (one per line) from STDIN and adds them to filename. The passwords already has to be crypted.
update
Same as the "adduser" command, except that it makes sure username already exists in filename.
view
Just displays the complete contents of the DBM file.
username
The user for which the update operation is performed.

BUGS

One should be aware that there are a number of different DBM file formats in existance, and with all likelihood, libraries for more than one format may exist on your system. The three primary examples are 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 dbmmanage expects to see. dbmmanage currently has no way of determining what type of DBM file it is looking at. If used against the wrong format, dbmmanage 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, and then GDBM. 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.

Apache's mod_auth_db.c module corresponds to Berkeley DB 2 library, while mod_auth_dbm.c corresponds to the NDBM library. Also, one can usually use the file program supplied with most Unix systems to see what format a DBM file is in.

Il est vrai que je n'ai pas utilis? la commande mount.
Toutefois, je ne sais pas ou il faut la tapper.
