       slappasswd - OpenLDAP password utility


       /usr/lib/ultrapossum/slapd/sbin/slappasswd   [-v]  [-u]  [-s  secret|-T
       file] [-h hash] [-c salt-format]


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


       -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
              exclusive 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}.

              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
              latter 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
              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  algorithm  and provides 8 random
              characters of salt.  The default  is  "%s",  which  provides  31
              characters of salt.


       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).

       It should also be noted that the behavior of
              crypt(3) is platform specific.


       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.
