SYNOPSIS
     ldappasswd  [-V[V]]  [-d debuglevel] [-n] [-v] [-A] [-a oldPasswd] [-t old-
     passwdfile] [-S] [-s newPasswd] [-T newpasswdfile]  [-x]  [-D binddn]  [-W]
     [-w passwd]     [-y passwdfile]	 [-H ldapuri]	  [-e [!]ext[=extparam]]

DESCRIPTION
     ldappasswd  is a tool to set the password of an LDAP user.  ldappasswd uses
     the LDAPv3 Password Modify (RFC 3062) extended operation.

     ldappasswd sets the password of associated with the user [or an  optionally
     specified	user].	If the new password is not specified on the command line
     and the user doesn't enable prompting, the server will be asked to generate
     a password for the user.

     ldappasswd is neither  designed  nor  intended  to  be  a	replacement  for
     passwd(1) and should not be installed as such.

OPTIONS
     -V[V]  Print  version  info.  If -VV is given, only the version information
	    is printed.

     -d debuglevel
	    Set the LDAP debugging level to debuglevel.  ldappasswd must be com-
	    piled with LDAP_DEBUG defined for this option to have any effect.

     -n     Do not set password. (Can be useful when used in conjunction with -v
	    or -d)

     -v     Increase the verbosity of output.  Can be specified multiple times.

     -A     Prompt for old password.  This is used  instead  of  specifying  the
	    password on the command line.

     -a oldPasswd
	    Set the old password to oldPasswd.

     -t oldPasswdFile
	    Set the old password to the contents of oldPasswdFile.

     -S     Prompt  for  new  password.   This is used instead of specifying the
	    password on the command line.

     -s newPasswd
	    Set the new password to newPasswd.

     -T newPasswdFile
	    Set the new password to the contents of newPasswdFile.

     -x     Use simple authentication instead of SASL.

     -D binddn
	    Use the Distinguished Name binddn to bind  to  the	LDAP  directory.
	    For SASL binds, the server is expected to ignore this value.

     -W     Prompt  for  bind  password.  This is used instead of specifying the
	    password on the command line.

     -w passwd
	    Use passwd as the password to bind with.

     -y passwdfile
	    Use complete contents of passwdfile as the password for  simple  au-
	    thentication.

     -H ldapuri
	    Specify  URI(s)  referring	to  the  ldap server(s); only the proto-
	    col/host/port fields are allowed; a list of URI, separated by white-
	    space or commas is expected.

     -e [!]ext[=extparam]

     -E [!]ext[=extparam]

	    Specify general extensions with -e and passwd modify extensions with
	    -E.  '!' indicates criticality.

	    General extensions:
	      [!]assert=<filter>    (an RFC 4515 Filter)
	      !authzid=<authzid>    ("dn:<dn>" or "u:<user>")
	      [!]bauthzid	    (RFC 3829 authzid control)
	      [!]chaining[=<resolve>[/<cont>]]
	      [!]manageDSAit
	      [!]noop
	      ppolicy
	      [!]postread[=<attrs>] (a comma-separated attribute list)
	      [!]preread[=<attrs>]  (a comma-separated attribute list)
	      [!]relax
	      sessiontracking[=<username>]
	      abandon,cancel,ignore (SIGINT sends abandon/cancel,
	      or ignores response; if critical, doesn't wait for SIGINT.
	      not really controls)

	    Passwd Modify extensions:
	      (none)

     -o opt[=optparam]]

	    Specify any ldap.conf(5) option or one of the following:
	      nettimeout=<timeout>  (in seconds, or "none" or "max")
	      ldif_wrap=<width>     (in columns, or "no" for no wrapping)

     -O security-properties
	    Specify SASL security properties.

     -I     Enable SASL Interactive mode.  Always prompt.  Default is to  prompt
	    only as needed.

     -Q     Enable SASL Quiet mode.  Never prompt.

     -N     Do not use reverse DNS to canonicalize SASL host name.

     -U authcid
	    Specify  the authentication ID for SASL bind. The form of the ID de-
	    pends on the actual SASL mechanism used.

     -R realm
	    Specify the realm of authentication ID for SASL bind.  The	form  of
	    the realm depends on the actual SASL mechanism used.

     -X authzid
	    Specify  the requested authorization ID for SASL bind.  authzid must
	    be one of the following formats: dn:<distinguished name> or u:<user-
	    name>.

     -Y mech
	    Specify the SASL mechanism to be used for  authentication.	If  it's
	    not specified, the program will choose the best mechanism the server
	    knows.

     -Z[Z]  Issue StartTLS (Transport Layer Security) extended operation. If you
	    use -ZZ, the command will require the operation to be successful
