## 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 compiled 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 authentication.
    
           **-H** _ldapuri_
                  Specify URI(s) referring to the ldap server(s); only the
                  protocol/host/port fields are allowed; a list of URI,
                  separated by whitespace 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 depends 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:**_< username>_**.**
    
           **-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
