Sun Java System Access Manager 7.1 Administration Reference

Quota Constraints

Enables or disables session quota constraints. The enforcement of session quota constraints enables administrators to limit a user to have a specific number of active/concurrent sessions based on the constraint settings at the global level, or the configurations associated with the entities (realm/role/user) to which this particular user belongs.

The default setting for this attribute is OFF. You must restart the server if the settings are changed.
