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 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 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 pass-words.dat passwords.dat
              words.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 passwords.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 pass-words passwords
              words 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 partic-ular particular
              ular record only. dbmmanage passwords.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 for-mat format
       mat 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, 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 lan-guages, languages,
       guages, 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.
