A resource limits policy defines the maximum resources that Directory Proxy Server can process for a given connection handler. By using this type of connection handler policy, you can limit the resources allocated to connections, requests, and referrals.
A connection handler can have zero or one resource limits policy. If no resource limits policy is defined, no limits are applied to connections, requests and referrals. For information about how to configure resource limits policies and examples of resource limits policies, see Creating and Configuring a Resource Limits Policy in Sun Directory Server Enterprise Edition 7.0 Administration Guide.
The following list summarizes the resource limits that can be configured:
Maximum number of connections.
Maximum number of simultaneous connections from a single client.
Maximum number of operations per connection. If a client exceeds the maximum number of operations on one connection, the connection is closed by Directory Proxy Server.
Maximum number of simultaneous operations per connection.
If the maximum number of simultaneous operations per connection is 1, clients must perform synchronous operations. Additional requests for simultaneous operations, except for requests to abandon an operation, will fail with a Server Busy error.
Maximum permitted size of a search operation result
Maximum permitted duration of a search operation
Minimum length of a substring allowed in a search filter
Customized search limits, described in Customized Search Limits
Maximum number of hops when following referrals
Bind policy to be applied when referrals are followed:
Use password if supplied, else follow the referral as anonymous
Always follow the referral as anonymous
Policy applied when a referral is returned by the server:
Forward referrals to the client

Customized limits can be defined for search operations, based on the search base and search scope. If the target DN of a search is specified in a list, and the scope of a search is one-level or subtree, the maximum size of the search result can be configured.
Custom search limits are defined for a specific resource limits policy. If the resource limits policy is deleted, the custom search limits defined for that policy are also deleted. If custom search limits are not specified, standard search size limits are applied.
