[TYPO3-dev] three TYPO3 website and one auth service

[Bartosz Aninowski]

I want to implement single user database for 3 websites.
I want to store only user and password not website specific data.
For example:
1. user A creates account in web1
2. plugin checks if user already exist in external database
3. new user and password are inserted in external database
4. rest of data are stored in local fe_user table

Has anoyone of you done this before?
Any hints?
