4.12 ldapmodifymt

The ldapmodifymt command-line tool is similar to ldapmodify in that it enables you to add, delete, or modify entries by supplying an LDIF file as input. However, ldapmodifymt runs in multi-threaded mode allowing you to operate on multiple entries concurrently.

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

4.12.1 Syntax for ldapmodifymt

ldapmodifymt -h oid_hostname -D "binddn" -w password [-p ldap_port]  [-V ldap_version] -T number_of_threads {-f ldif_filename | -X dsml_filename}   [-a] [-b] [-c [-o log_file_name]] [-M] [-O ref_hop_limit] [-k|-K]  [-U SSL_auth_mode {-W wallet_location -P wallet_password}] [-E character_set]  [-d debug_level]

4.12.2 Arguments for ldapmodifymt

-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).

-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).

-T number_threads

Required. The number of threads for concurrently processing entries.

-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.


Optional. Denotes that the LDIF file has entries to be added.


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.


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.

-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.


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.

-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

4.12.3 Tasks and Examples for ldapmodifymt

Using the ldapmodifymt command-line tool, you can perform the following task: Modifying Multiple Entries Concurrently

To modify multiple entries at once, you must first prepare your LDIF file correctly. See Appendix A, "LDIF File Format" for examples. Once you have a properly formatted LDIF file, you can use the ldapmodifymt tool to import the changes.

The following example uses five concurrent threads to modify the entries specified in the file /home/myfiles/modify.ldif.


ldapmodify -h -D "cn=orcladmin" -w password -p 389  -T 5 -f /home/myfiles/modify.ldif  -v
