User pool is a concept for improving the performance and for the efficient use of resources.
Starting from V 6.2 the project's parameter values are reset to the template project's parameter value when the session starts.
Starting from V 6.4 the user pool clones have the APPID in their names, so <webuser>-<appid>-<rand>, e.g. ESSUSER-1062-2355365.
Existing user pool clones are listed in the Admin Portlet and can be deleted there.
The AccountId shows if a clone is currently in use and of what context.
User pool with ESS
TIS Board pages may be integrated into ESS. Employees can log into ESS by their Employee-Number and Web-Password. The assigned Web-User defines the user pool. For concurrent sessions user pool clones are generated, having the same set of roles as the Web-User.
