Exchange and AD

["Shamblin, Quinn (shamblqn)" <shamblqn () UCMAIL UC EDU>]

Hello everyone,
 
I would like to understand the approaches that different organizations use for a certain aspect of Identity Management.
 
For those of you out there that are running Exchange and use Active Directory to manager your accounts, how are you 
expiring your user accounts?  How do you manage the expiry of normal users, yet have system or shared accounts that do 
not expire?
 
I apprciate any window you can give me on your approach.  Thanks,
 
Regards,
