SLAPPASSWD(8C)                                                                                SLAPPASSWD(8C)



NAME
       slappasswd - OpenLDAP password utility

SYNOPSIS
       /BinaryCache/OpenLDAP/OpenLDAP-106~5/Root/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 gen-erate generate
              erate 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.

LIMITATIONS
       The practice storing hashed passwords in userPassword violates Standard Track (RFC 2256) schema spec-ifications specifications
       ifications and may hinder interoperability.  A new attribute type, authPassword, to hold hashed pass-words passwords
       words 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.

SECURITY CONSIDERATIONS
       Use of hashed passwords does not protect passwords during protocol transfer.  TLS or other eavesdrop-ping eavesdropping
       ping protections should be in-place before using LDAP simple bind.

       The hashed password values should be protected as if they
              were clear text passwords.
