Hello!

The tac_plus user guide says that when passwd(5) file is used for user
authentication, the expiry date checks against shell field of password file.
Maybe it is OK for custom passwd files, but not for system password file.

Here is a little patch below which allow the tacacs daemon check
the expiration dates against 'expire' field of FreeBSD's master.passwd file.
It is very useful for me, and may be useful for other FreeBSD&tacacs users.

With best regards,
Sergey Levov (serg@informika.ru)
