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
