19 is used to generate an userPassword value
25 configuration directive.
32 Generate RFC 2307 userPassword values (the default). Future
33 versions of this program may generate alternative syntaxes
34 by default. This option is provided for forward compatibility.
37 The secret to hash. If not provided, the user will be prompted
38 for the secret to hash.
41 If -h is specified, one of the following RFC 2307 schemes may
54 use the SHA-1 algorithm (FIPS 160-1), the latter with a seed.
59 use the MD5 algorithm (RFC 1321), the latter with a seed.
66 indicates that the new password should be added to userPassword as
69 .BI \-c " crypt-salt-format"
70 Specify the format of the salt passed to
72 when generating {CRYPT} passwords.
73 This string needs to be in
75 format and may include one (and only one) %s conversion.
76 This conversion will be substituted with a string random
77 characters from [A\-Za\-z0\-9./]. For example, "%.2s"
78 provides a two character salt and "$1$%.8s" tells some
79 versions of crypt(3) to use an MD5 algorithm and provides
80 8 random characters of salt. The default is "%s", which
81 provides 31 characters of salt.
83 The practice storing hashed passwords in userPassword violates
84 Standard Track (RFC 2256) schema specifications and may hinder
85 interoperability. A new attribute type, authPassword, to hold
86 hashed passwords has been defined (RFC 3112), but is not yet
89 .SH "SECURITY CONSIDERATIONS"
90 Use of hashed passwords does not protect passwords during
91 protocol transfer. TLS or other eavesdropping protections
92 should be inplace before using LDAP simple bind. The
93 hashed password values should be protected as if they
94 were clear text passwords.
