[-K keyfile] [-m mechanism] [-M] [-N certificatename]

[-U username] [-v] [-V version] [-y proxydn] [-Y] [-Z] [-?]

Description

Sends modify password requests to an LDAP server. Allows the password for a directory entry to be changed.

Options

-C charset
Specifies that the DNs supplied as input to the ldapdelete utility are represented in a local character set, as specified by charset. Use the -C charset option if the input string codepage is different from the job codepage value. Refer to the ldap_set_iconv_local_charset() API to see supported charset values.
-d debuglevel
Set the LDAP debugging level to debuglevel.
-D binddn
Use binddn to bind to the LDAP directory. binddn is a string-represented DN. When used with -m DIGEST-MD5, it is used to specify the authorization ID. It can either be a DN, or an authzId string starting with "u:" or "dn:".
-G realm
Specify the realm. This parameter is optional. When used with -m DIGEST-MD5, the value is passed to the server during the bind.
-h ldaphost
Specify an alternate host on which the ldap server is running.
-K keyfile
Specify the name of the SSL key database file. If the key database file is not in the current directory, specify the fully-qualified key database filename.

If the utility cannot locate a key database, it will use a hard-coded set of default trusted certificate authority roots. The key database file typically contains one or more certificates of certification authorities (CAs) that are trusted by the client. These types of X.509 certificates are also known as trusted roots.

This parameter effectively enables the -Z switch. For Directory Server on i5/OS if you use -Z and do not use -K or -N, the certificate associated with the Directory Services Client application ID will be used.

-m mechanism
Use mechanism to specify the SASL mechanism to be used to bind to the server. The ldap_sasl_bind_s() API is used. The -m parameter is ignored if -V 2 is set. If -m is not specified, simple authentication is used. Valid mechanisms are:
-M
Manage referral objects as regular entries.
-n newpassword | ?
Specifies the new password. Use the ? to generate a password prompt.
-N certificatename
Specify the label associated with the client certificate in the key database file. If the LDAP server is configured to perform server authentication only, a client certificate is not required. If the LDAP server is configured to perform client and server authentication, a client certificate might be required. certificatename is not required if a default certificate/private key pair has been designated as the default. Similarly, certificatename is not required if there is a single certificate/private key pair in the designated key database file. This parameter is ignored if neither -Z nor -K is specified. For Directory Server on i5/OS if you use -Z and do not use -K or -N, the certificate associated with the Directory Services Client application ID will be used.
-O maxhops
Specify maxhops to set the maximum number of hops that the client library takes when chasing referrals. The default hopcount is 10.
-p ldapport
Specify an alternate TCP port where the ldap server is listening. The default LDAP port is 389. If -p is not specified and -Z is specified, the default LDAP SSL port 636 is used.
-P keyfilepw
Specify the key database password. This password is required to access the encrypted information in the key database file, which can include one or more private keys. If a password stash file is associated with the key database file, the password is obtained from the password stash file, and the -P parameter is not required. This parameter is ignored if neither -Z nor -K is specified.
-R
Specifies that referrals are not to be automatically followed.
-U username
Specify the username. Required with -m DIGEST-MD5 and ignored with any other mechanism.
-v
Use verbose mode, with many diagnostics written to standard output.
-V version
Specifies the LDAP version to be used by ldapdchangepwd when it binds to the LDAP server. By default, an LDAP V3 connection is established. To explicitly select LDAP V3, specify -V 3. Specify -V 2 to run as an LDAP V2 application. An application, like ldapdchangepwd, selects LDAP V3 as the preferred protocol by using ldap_init instead of ldap_open.
-w passwd | ?
Use passwd as the password for authentication. Use the ? to generate a password prompt.
-y proxydn
Set proxied ID for proxied authorization operation.
-Y
Use a secure LDAP connection (TLS).
-Z
Use a secure SSL connection to communicate with the LDAP server. For Directory Server on i5/OS if you use -Z and do not use -K or -N, the certificate associated with the Directory Services Client application ID will be used.
-?
Displays the syntax help for ldapchangepwd.

Examples

The following command, 

ldapchangepwd -D cn=John Doe -w a1b2c3d4 -n wxyz9876

changes the password for the entry named with commonName "John Doe" from a1b2c3d4 to wxyz9876

Diagnostics

Exit status is 0 if no errors occur. Errors result in a non-zero exit status and a diagnostic message being written to standard error.
