LDAPPASSWD(1)

NAME
ldappasswd - change the password of an LDAP entry

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); 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.

-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
