.SH DESCRIPTION
.LP
.B Slappasswd
is used to generate an userPassword value
suitable for use with
.BR ldapmodify (1),
.BR slapd.conf (5)
.I rootpw
configuration directive or the 
.BR slapd\-config (5) 
.I olcRootPW
configuration directive.
.
.SH OPTIONS
.TP
.B \-v
enable verbose mode.
.TP
.B \-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.
.TP
.BI \-s \ secret
The secret to hash.
If this,
.B \-g
and
.B \-T
are absent, the user will be prompted for the secret to hash.
.BR \-s ,
.B \-g
and
.B \-T
are mutually exclusive flags.
.TP
.BI \-g
Generate the secret.
If this,
.B \-s
and
.B \-T
are absent, the user will be prompted for the secret to hash.
.BR \-s ,
.B \-g
and
.B \-T
are mutually exclusive flags.
If this is present,
.I {CLEARTEXT}
is used as scheme.
.B \-g
and
.B \-h
are mutually exclusive flags.
.TP
.BI \-T \ "file"
Hash the contents of the file.
If this,
.B \-g
and
.B \-s
are absent, the user will be prompted for the secret to hash.
.BR \-s ,
.B \-g
and
.B \-T
and mutually exclusive flags.
.TP
.BI \-h \ "scheme"
If \fB\-h\fP is specified, one of the following RFC 2307 schemes may
be specified:
.BR {CRYPT} ,
.BR {MD5} ,
.BR {SMD5} ,
.BR {SSHA} ", and"
.BR {SHA} .
The default is 
.BR {SSHA} .

Note that scheme names may need to be protected, due to
.B {
and
.BR } ,
from expansion by the user's command interpreter.

.B {SHA}
and
.B {SSHA}
use the SHA-1 algorithm (FIPS 160-1), the latter with a seed.

.B {MD5}
and
.B {SMD5}
use the MD5 algorithm (RFC 1321), the latter with a seed.

.B {CRYPT}
uses the
.BR crypt (3).

.B {CLEARTEXT}
indicates that the new password should be added to userPassword as
clear text.
Unless
.I {CLEARTEXT}
is used, this flag is incompatible with option
.BR \-g .
.TP
.BI \-c \ crypt-salt-format
Specify the format of the salt passed to
.BR crypt (3)
when generating {CRYPT} passwords.  
This string needs to be in
.BR sprintf (3)
format and may include one (and only one)
.B %s
conversion.
This conversion will be substituted with a string of random
characters from [A\-Za\-z0\-9./].  For example,
.RB ' %.2s '
provides a two character salt and
.RB ' $1$%.8s '
tells some
versions of
.BR crypt (3)
to use an MD5 algorithm and provides
8 random characters of salt.
The default is
.RB ' %s ' ,
which provides 31 characters of salt.
.TP
.BI \-n
Omit the trailing newline; useful to pipe the credentials
into a command.
.TP
.BI \-o \ option\fR[ = value\fR]
Specify an
.I option
with a(n optional)
.IR value .
Possible generic options/values are:
.LP
.nf
              module\-path=<pathspec> (see `\fBmodulepath\fP' in slapd.conf(5))
              module\-load=<filename> (see `\fBmoduleload\fP' in slapd.conf(5))

.in
You can load a dynamically loadable password hash module by
using this option.
.SH LIMITATIONS
The practice of storing hashed passwords in userPassword violates
Standard Track (RFC 4519) 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
.BR slapd (8).
.LP
It should also be noted that the behavior of
.BR crypt (3)
is platform specific.
.SH "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.
.LP
The hashed password values should be protected as if they
were clear text passwords.
