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 general options.
General options:
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
