NAME
       slappasswd - OpenLDAP password utility

SYNOPSIS
       /usr/sbin/slappasswd  [-v] [-u] [-s secret|-T file] [-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	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 and -T are absent, the user will be
	      prompted for the secret to hash.	-s and -T and mutually	exclu‐
	      sive flags.

       -T file
	      Hash  the	 contents of the file.	If this and -s are absent, the
	      user will be prompted for the secret to hash.   -s  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}.

	      {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.

       -c crypt-salt-format
	      Specify the format of the salt passed to crypt(3) when  generat‐
	      ing  {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  charac‐
	      ter salt and "$1$%.8s" tells some versions of crypt(3) to use an
	      MD5 algorithm 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 (RFC 2256) schema specifications and may hinder interoperability.
       A  new  attribute type, authPassword, to hold hashed passwords has been
       defined (RFC 3112), but is not yet implemented in slapd(8).

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.
