     SYNOPSIS
          ldappasswd [-A] [-a oldPasswd] [-t oldpasswdfile]
          [-D binddn] [-d debuglevel] [-H ldapuri] [-h ldaphost] [-n]
          [-p ldapport] [-S] [-s newPasswd] [-T newpasswdfile] [-v]
          [-W] [-w passwd] [-y passwdfile] [-O security-properties]
          [-I] [-Q] [-U authcid] [-R authcid] [-x] [-X authzid]
          [-R realm] [-Y mech] [-Z[Z]] [user]

     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
          -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.

          -x   Use simple authentication instead of SASL.

          -D binddn
               Use the Distinguished Name binddn to bind to the LDAP
               directory.

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

          -H ldapuri
               Specify URI(s) referring to the ldap server(s).

          -h ldaphost
               Specify an alternate host on which the ldap server is
               running.  Deprecated in favor of -H.

          -p ldapport
               Specify an alternate TCP port where the ldap server is
               listening.  Deprecated in favor of -H.

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

          -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.

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

          -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.

          -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.

          -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:<distinguishedname> 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
