access for 24 hours after first login?

[Markus Krause]

hello list,

i set up freeradius succesfully for authentification against pam and users file
:-)
now i want to enhance the functionality about the following feature:
setting up several predefined (guest) accounts with a generated username and
password. this account should be valid from the first time it is used (first
login)   for 24 hours (or even better until 23:59 that day). this is intended
for our daily visitors and guests or for conference members, the idea is to
give them a username/password pair to be used just that day without much
administration effort. (just generate a list of lets say 100 accounts and if
they have been used just create new ones).

(how) can this be realized using freeradius? has anyone set up a similar (or
even better ;-) ) solution for this aim? (one-day passwords valid after first
login)

thanks for any help and hints!

regards,
   markus
