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] [-h ldaphost] [-p ldapport] [-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.

-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.

-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


  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
