Importing users from large data sets is very slow

Crowd has a problem with importing large sets of users. The import process will be very slow and may time out. This issue is being tracked as CWD-848. As a workaround, we recommend importing from data sets of maximum 1000 users.

You can copy users from an external directory or user base into Crowd via a CSV (comma-separated values) file. There are two phases involved:

  1. Export your existing users and their group memberships from your external directory into a CSV file or files.
  2. Import the users, groups and group memberships into a Crowd directory from the CSV files.

(info) The CSV importer is available with Crowd 1.1.1 and later.

Preparing your CSV Files

You will need:

  • a CSV file containing user information, and
  • optionally, another CSV file containing group memberships.

Attached are simple examples of the CSV files:

The CSV Importer's 'File Mappings' screen allows you to match the CSV fields to Crowd's User and Group fields.

Formatting and location of the CSV files:

要件

説明

場所

The CSV files must be on the local drive (e.g. C:) of the Crowd server.

Supported attributes

The CSV Importer does not support custom attributes. The supported attributes are shown in the drop-down lists on the 'File Mappings' screen.

ヘッダーの行

The first row in each CSV file must be a header row. The CSV Importer will not import the information in the first row. The information in the first row is displayed in the column labelled 'CSV Header Row' on the 'File Mappings' screen

区切り文字

The fields in the CSV file must be separated by a single-character delimiter. The CSV Importer's 'Configuration' screen lets you tell Crowd which delimiter you have used.

パスワード

You will need to decide whether to import your passwords into Crowd. And if you do import the passwords, you must choose to import them as either encrypted or clear text. (warning) Check the password encryption in the directory you are exporting users from, and compare it with the encryption method of the Crowd directory you want to import the users into. You can use Crowd's Directory Browser to view the directory's configuration details, including the encryption method. The CSV Importer's 'Configuration' screen lets you tell the CSV Importer whether to encrypt the passwords.

To export information from your user directory into a CSV file,

  1. Export the users from your external user directory or database into a CSV file. Your directory or user base should have an option to allow you to do this.
  2. If you want to copy your existing group memberships into Crowd, export the groups and group memberships into another CSV file.

Importing the CSV Files into Crowd

Once you have prepared your CSV file(s), you can import the users and groups into a Crowd directory.

To import users and groups from CSV files,

  1. Log in to the Crowd Administration Console.
  2. Click the 'Users' link in the top navigation bar.
  3. This will display the User Browser. Click the 'Import Users' link.
  4. This will display the 'Import Type' screen. Click the 'CSV Importer' button.
  5. This will display the 'Configuration' tab of the 'CSV Importer'.
  6. Enter the details of the CSV files as described in 'Configuring the CSV Importer'.
