[FreeRadius] Help how do I make Expiration

[Horas Hajovan Siregar]

Hello @Alan DeKok

I mean
If we use the Expiration attribute in FreeRADIUS, the format is an 
absolute date and time, for example:
'23 Aug 2025 22:30:00'
The problem: This expiration cannot be calculated automatically per 
login. If you set it directly in radcheck, the user will expire at a 
specific time, not relative to the first login.

Is there a way to automatically expire a user within the next day upon 
first login, and the user cannot be reused after 1 day?
