Account Expire Date...

Have configured RouterOS 2.9 with freeradius and mysql database.
Is there a way to set an expire date / time for an account? in other words,users can’t use the account after the expire date / time?

thx.

Session-time is attribute to set timeout for client, after this time the user will be logged out unconditionally.

i mean that how can i set attribute to a user in order to let it expired automatically.
i was set attribute(Expiration) to a user,but it didn’t work.
anyone can help me?

which attribute you have used ?

attribute:Expiration
i have active the expiration module in the radiusd.conf(defined in default).

As far as I know, session-timeout is designed for this,
