account expiration attribute

[Rakotomandimby Mihamina]

Hi all,

What RADIUS attribute would suit to account expiration?
the context:

- prepaid users must regularily add credit to his account
- big credit ->  big validity extension
- small credit -> small validity extension
- no account removal, just auth reject if validity date passed

Credit adding and account validity extension is not managed
by the RADIUS stuff, it's about a manual external insert

What we just need is the right RADIUS attribute to be checked
during auth, in order to reject if the date is passed.

Thanks for any help.
