Crowd 2.1 Beta Guide to LDAP Connection Pooling
This page contains an overview of the new connection pool for LDAP directories in Crowd 2.1 Beta 2.
When connection pooling is enabled, the LDAP service provider maintains a pool of connections and assigns them as needed. When a connection is closed, LDAP returns the connection to the pool for future use. This can improve performance significantly.
This page describes the site-wide settings for LDAP connection pooling in Crowd.
To configure the LDAP connection pooling in Crowd,
- Log in to the Crowd Administration Console.
- Click the 'Administration' tab in the top navigation bar.
- Click 'LDAP Connection Pool' in the left-hand menu.
- The 'LDAP Connection Pool' screen appears. Enter the details for each setting, as described in the table below.
- Click the 'Update' button.
- Restart Crowd to put the changes into effect.
