4.11 ldapmodify

The ldapmodify command-line tool enables you to add, delete, or replace attributes for entries by supplying an LDIF file as input. You can also delete or add entries using ldapmodify.

See Appendix A, "LDIF File Format" for more information about the correct formatting of LDIF files.

4.11.1 Syntax for ldapmodify

ldapmodify -h oid_hostname -D "binddn" [-Y "proxy_dn"] -w password [-p ldap_port] [-V ldap_version] {-f ldif_filename | -X dsml_filename}  [-a] [-b]  [-c [-o log_file_name]] [-n] [-v] [-M] [-O ref_hop_limit] [-i 1|0] [-k|-K]  [-U SSL_auth_mode {-W wallet_location -P wallet_password}] [-E character_set]  [-d debug_level]

4.11.2 Arguments for ldapmodify

-h oid_hostname

Required. The host name or IP address of the Oracle Internet Directory server.

-D "binddn"

Required. The DN of the Oracle Internet Directory user needed to bind to the directory (for example, cn=orcladmin).

-Y "proxy_dn"

Optional. The DN of a proxy user. After binding to the directory, the add operation will be performed as this user.

-w password

Required. The user password needed to bind to the directory.

-p ldap_port

Optional. The port number used to connect to the Oracle Internet Directory server. Defaults to port 389.

-V ldap_version

Optional. The version of the LDAP protocol to use. Allowed values are 2 or 3. Defaults to 3 (LDAP v3).

-f ldif_filename | -X dsml_filename

Required. The full path and file name of the input file that contains the data you want to import.

Use the -f argument to supply an LDIF file. See Appendix A, "LDIF File Format" for information on formatting an LDIF file.

Use the -X argument to supply a Directory Service Markup Language (DSML) file. See "Adding Data to the Directory Using a DSML File" for more information about formatting a DSML file.

-a

Optional. Denotes that the LDIF or DSML input file has new entries to be added.

-b

Optional. Use this option if your input file has binary file names in it, which are preceded by the forward slash character. The tool retrieves the actual values from the file referenced.

-c

Optional. Proceeds in spite of errors. All errors will be reported. If the -c argument is not used, the tool will stop when an error occurs.

-n

Optional. Enables you to preview what would occur in an operation without actually performing the operation.

-v

Optional. Runs the tool in verbose mode.

-o log_file_name

Optional. Used with the -c argument. Writes the LDIF entries with errors to a log file. Specify the full path and name of the log file.

-M

Optional. Instructs the tool to send the ManageDSAIT control to the server. The ManageDSAIT control instructs the server not to send referrals to clients. Instead a referral entry is returned as a regular entry.

-O ref_hop_limit

Optional. The number of referral hops that a client should process. Defaults to 5.

-i 1 | 0

Optional. Specifies whether or not to bind as the current user when following referrals. 1 means bind as the current user, 0 means bind anonymously. The default is 0 (zero).

-k | -K

Optional. The -k argument authenticates using Kerberos authentication instead of simple authentication. To enable this option, you must compile with KERBEROS defined.You must already have a valid ticket granting ticket. Use the -K argument if you want to only perform the first step of the Kerberos bind.

-U SSL_auth_mode

Optional. The SSL authentication mode:

1 for no authentication required.
2 for one way authentication required. You must also supply a wallet location and wallet password.
3 for two way authentication required. You must also supply a wallet location and wallet password.

-W wallet_location

Required if using one way or two way SSL authentication (-U 2|3). The location of the wallet file that contains the server's SSL certificates.

Example for UNIX:

-W "file:/home/my_dir/my_wallet"

Example for Microsoft Windows:

-W "file:C:\my_dir\my_wallet"

-P wallet_password

Required if using one way or two way SSL authentication (-U 2|3). The wallet password for the wallet specified in the -W argument.

-E character_set

Optional. The native character set encoding. Defaults to the character set of the user's terminal. Each supported character set has a unique acronym, for example, WE8MSWIN1252, JA16SJIS, or AL32UTF8.

-d debug_level

Optional. If not specified the default of 0 (not enabled) is used. Debug levels are additive. Add the numbers representing the functions that you want to activate, and use the sum of those in the command-line option. For example, to trace search filter processing (512) and active connection management (256), enter 768 as the debug level (512 + 256 = 768). Debug levels are as follows:

1 — Heavy trace debugging
128 — Debug packet handling
256 — Connection management, related to network activities
512 — Search filter processing
1024 — Entry parsing
2048 — Configuration file processing
8192 — Access control list processing
491520 — Log of communication with the database
524288 — Schema related operations
4194304 — Replication specific operations
8388608 — Log of entries, operations and results for each connection
16777216 — Trace function call arguments
67108864 — Number and identity of clients connected to this server
117440511 — All possible operations and data

4.11.3 Tasks and Examples for ldapmodify

Using the ldapmodify command-line tool, you can perform the following tasks:

Modifying the Directory Schema
Modifying an Entry

4.11.3.1 Modifying the Directory Schema

First, you must prepare your LDIF file to define the new schema elements you want to add. See "LDIF Format for Adding Schema Elements" for examples. Once you have a properly formatted LDIF file, you can use the ldapmodify tool to import the new schema definitions into the directory schema.

Example:

ldapmodify -h myhost.company.com -D "cn=orcladmin" -w password -p 389  -f /home/myfiles/modify.ldif  -v

4.11.3.2 Modifying an Entry

To modify the attributes or attribute values for an entry, you must first prepare your LDIF file correctly. See "LDIF Format for Modifying Entries" for examples. Once you have a properly formatted LDIF file, you can use the ldapmodify tool to import the changes.
