Documentation for Crowd 2.2. Documentation for other versions of Crowd is available too.

This page provides notes for configuring an LDAP directory using the Posix/NIS schema RFC 2307. This page is related to Configuring an LDAP Directory Connector.

Crowd supports read-only connections to an LDAP directory using the Posix/NIS schema. This is useful if you have a Unix installation and want to integrate with an LDAP directory. The Posix/NIS schema allows integration between an LDAP directory and the Unix NIS (Network Information Service).

Crowd's Posix support is read-only

Currently, Crowd supports read-only access to the directory based on the Posix schema. You cannot add or update user details.

属性

説明

Connector

The directory connector to use when communicating with the directory server.

URL

The connection URL to use when connecting to the directory server, e.g.: ldap://localhost:389, or port 636 for SSL.

Secure SSL

Specifies if the connection to the directory server is a SSL connection.

Use Node Referrals

Use the JNDI lookup java.naming.referral option. Generally needed for Active Directory servers configured without proper DNS, to prevent a 'javax.naming.PartialResultException: Unprocessed Continuation Reference(s)' error.

Use the User Membership Attribute

Put a tick in the checkbox if your directory supports the group membership attribute on the user. (By default, this is the 'memberOf' attribute.) For instructions on enabling this feature in your directory, please refer to the OpenLDAP documentation.

  • If this checkbox is ticked, Crowd will use the group membership attribute on the user when retrieving the members of a given group. This will result in a more efficient retrieval.
  • If this checkbox is not ticked, Crowd will use the members attribute on the group ('member' by default) for the search.

ページングされた結果を使用

Use the LDAP control extension for simple paged results option. Retrieves chunks of data rather than all of the results at once. This feature may be necessary when using Microsoft Active Directory if more than 999 results are returned for any given search.

Use Naive DN Matching

This setting determines how Crowd will compare DNs to determine if they are equal. See Using Naive DN Matching.

  • If this checkbox is ticked, Crowd will do a direct, case-insensitive, string comparison. This is the default and recommended setting for Posix schemas. Using relaxed DN standardisation will result in a significant performance improvement.
  • If this checkbox is not ticked, Crowd will parse the DN and then check the parsed version.

Polling Interval

Crowd will send a request to LDAP every x minutes, where 'x' is the number specified here. Please read the full instructions: Configuring Caching for an LDAP Directory.

Read Timeout

Time in seconds to wait for a response to be received. If there is no response within the specified time period, the read attempt will be aborted. A value of 0 (zero) means there is no limit.

Search Timeout

Time in seconds to wait for a response from a search operation. A value of 0 (zero) means there is no limit.

コネクション タイムアウト

Timeout in seconds when opening new server connections. If not specified, the TCP network timeout will be used, which may be several minutes.

Password Encryption

Select the type of encryption that the directory uses.

ベース DN

Enter the root distinguished name to use when running queries versus the directory server, e.g.: o=acmecorp,c=com.

ユーザー DN

Distinguished name of the user that Crowd will use when connecting to the directory server.

パスワード

上記で指定したユーザーのパスワード。

Note: You can also configure site-wide LDAP connection pool settings. See Configuring the LDAP Connection Pool.

Group Relationships

Crowd は gidNumbermemberUid 属性の両方を確認し、ユーザーがグループのメンバーかどうかを判断します。gidNumber 属性の名前を変更することはできません。Crowd はメンバーシップの確認に必ずこの属性を使用します。

The RFC 2307 schema does not support nesting of groups, so Crowd does not support nested groups in the Posix schema.
