NAME

       slappasswd - OpenLDAP password utility

SYNOPSIS

       /usr/sbin/slappasswd [-v] [-u] [-s secret] [-h hash] [-c salt-format]

DESCRIPTION

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

OPTIONS

       -v     enable verbose mode.

       -u     Generate	RFC2307  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 not provided, the user will be prompted for the secret to hash.

       -h scheme
	      If -h is specified, one of the following RFC2307 schemes may be specified: {CRYPT}, {MD5}, {SMD5}, {SSHA}, and {SHA}.   The  default
	      is {SSHA}.

       -c crypt-salt-format
	      Specify  the  format of the salt passed to crypt(3) when generating {CRYPT} passwords.  This string needs to be in sprintf(3) format
	      and may include one (and only one) %s conversion.  This conversion  will	be  substituted  with  a  string  random  characters  from
	      [A-Za-z0-9./].   For example, "%.2s" provides a two character salt and "$1$%.8s" tells some versions of crypt(3) to use an MD5 algo-
	      rithm and provides 8 random characters of salt.  The default is "%s", which provides 31 characters of salt.

LIMITATIONS

       The practice storing hashed passwords in userPassword violates Standard Track (RFC2256) schema specifications and may hinder interoperabil-
       ity.  A new attribute type to hold hashed passwords is needed.

SECURITY CONSIDERATIONS

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