dbmmanage2




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. 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 per­
                     formed. 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 orig­
                     inal password untouched.

              group  A  group,  which  the  user  is member of. A

       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.

              adduser
                     Asks for a password and then adds  an  entry
                     for username to filename.

              check  Asks for a password and then checks if user­
                     name 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 have to be crypted.

              update Same  as the adduser command, except that it
                     makes sure username already exists in  file­
                     name.

              view   Just  displays the contents of the DBM file.
                     If you specify a username, it  displays  the
                     particular record only.


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 sys­
       tem. The three primary examples are SDBM,  NDBM,  the  GNU
       project's  GDBM,  and  Berkeley  DB  2. Unfortunately, all
       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 order­
       ing is slightly different than the  standard  @AnyDBM::ISA
       ordering in perl, as well as the ordering used by the sim­
       ple dbmopen() call in Perl, so if you use any other utili­
       ties  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.
