Background
================
I'm currently tasked with evaluating several self service password solutions. For those who don't know what this is, the software is in place so that users can reset/retrieve/change passwords without creating a helpdesk ticket or phone call. As an example, see the courion website: http://www.courion.com

Feedback Wanted
================
Now, I'm well aware of the security implications so please don't tell me why they are good or bad. I'm simply after input from anyone who is currently using a self service password solution. More specifically, has it reduced helpdesk calls, has the response by end users been positive, has it gotten banged up by auditors, does it integrate well with LDAP, AD, etc.. And finally, which solution are you using?

Thanks in advance.
