NAME
ldappasswd - change the password of an LDAP entry

SYNOPSIS
ldappasswd [-V[V]] [-d debuglevel] [-n] [-v] [-A] [-a oldPasswd] [-t oldpasswdfile] [-S] [-s newPasswd] [-T newpasswdfile] [-x] [-D binddn] [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-e [!]ext[=extparam]] [-E [!]ext[=extparam]] [-o opt[=optparam]] [-O security-properties] [-I] [-Q] [-N] [-U authcid] [-R realm] [-X authzid] [-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

-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
