ldappasswd - change the password of an LDAP entry
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]
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.
-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
ldap_sasl_bind(3), ldap_extended_operation(3), ldap_start_tls_s(3)
