    Command:

    slappasswd

    
    
    

    SYNOPSIS

           /usr/sbin/slappasswd   [-v]   [-u]   [-g|-s secret|-T file]   [-h hash]
           [-c salt-format] [-n] [-o option[=value]]
    
    
    

    DESCRIPTION

           Slappasswd is used to generate an userPassword value suitable  for  use
           with ldapmodify(1), slapd.conf(5) rootpw configuration directive or the
           slapd-config(5) olcRootPW configuration directive.
    
    
    

    OPTIONS

           -v     enable verbose mode.
    
           -u     Generate RFC 2307 userPassword  values  (the  default).   Future
                  versions  of  this  program may generate alternative syntaxes by
                  default.  This option is provided for forward compatibility.
    
           -s secret
                  The secret to hash.  If this, -g and -T  are  absent,  the  user
                  will  be  prompted  for  the  secret to hash.  -s, -g and -T are
                  mutually exclusive flags.
    
           -g     Generate the secret.  If this, -s and -T are  absent,  the  user
                  will  be  prompted  for  the  secret to hash.  -s, -g and -T are
                  mutually exclusive flags.  If this is  present,  {CLEARTEXT}  is
                  used as scheme.  -g and -h are mutually exclusive flags.
    
           -T "file"
                  Hash  the  contents of the file.  If this, -g and -s are absent,
                  the user will be prompted for the secret to hash.  -s, -g and -T
                  and mutually exclusive flags.
    
           -h "scheme"
                  If -h is specified, one of the following RFC 2307 schemes may be
                  specified: {CRYPT},  {MD5},  {SMD5},  {SSHA},  and  {SHA}.   The
                  default is {SSHA}.
    
                  Note that scheme names may need to be protected, due to { and },
                  from expansion by the user's command interpreter.
    
                  {SHA} and {SSHA} use the SHA-1 algorithm (FIPS 160-1), the  lat-
                  ter with a seed.
    
                  {MD5}  and  {SMD5}  use the MD5 algorithm (RFC 1321), the latter
                  with a seed.
    
                  {CRYPT} uses the crypt(3).
    
                  {CLEARTEXT} indicates that the new password should be  added  to
                  userPassword  as  clear  text.  Unless {CLEARTEXT} is used, this
                  flag is incompatible with option -g.
    
                  Specify an option with a(n optional)  value.   Possible  generic
                  options/values are:
    
                         module-path=<pathspec> (see 'modulepath' in slapd.conf(5))
                         module-load=<filename> (see 'moduleload' in slapd.conf(5))
    
                  You can load a dynamically loadable password hash module by
                  using this option.
    
    
    

    LIMITATIONS

           The practice of storing hashed passwords in userPassword violates Stan-
           dard Track (RFC 4519) schema specifications and may  hinder  interoper-
           ability.   A new attribute type, authPassword, to hold hashed passwords
           has been defined (RFC 3112), but is not yet implemented in slapd(8).
    
           It should also be noted that the behavior of crypt(3) is platform  spe-
           cific.
    
    
    

    SECURITY CONSIDERATIONS

           Use  of  hashed  passwords  does  not protect passwords during protocol
           transfer.  TLS or other eavesdropping protections  should  be  in-place
           before using LDAP simple bind.
    
           The  hashed  password  values should be protected as if they were clear
           text passwords.
