[Typo3-dev] Service for own authentication

[Joerg Schoppet]

Hi list,

I've to build for my company several extensions in typo3:
- service request tool (status tracking, different roles, 
email-integration, qms-functionality, folder creation, ...)
- logbook (what has when happen?)
- checklists (daily, weekly, monthly tasks)
- resource-calendar (who is when available)

Each of this extensions will only be accessible over the FE. And each of 
this extension needs special authentication requirements.

So I thought about my own service with a general base-class and then 
each extension can provide its own service sub-type.

Is this usefull or excessive?

For clarification:
This should not be an auth service for FE-login. This is handled with 
existing typo3-extension. It should regulates what a user can see and 
what he is allowed to modify inside an extension.

Thanks for constructive answers in advance.
