Let's assume there is a need for multiple instances of iteraplan. A common example is one production instance and one test instance.
There are now two possibilities to integrate those instances with iTURM for user and role management.
1. Use multiple iTURM instances
In this variant one iTURM instance is installed for each iteraplan instance. The advantage of this setup is the possibility to control which user can log into which iteraplan instance, and what roles they get in each iteraplan instance.
2. Use one iTURM instance
In this variant only one iTURM instance is installed. All iteraplan instances refer to the same iTURM database used by that one iTURM instance. This setup is recommended when users should have the same roles no matter what iteraplan instance they log into.
The advantage of this setup is reduced maintenance effort.
