I've been doing some development in ACCPAC CRM and had to struggle to find out how to delete ghost login sessions when all my user licenses got used up due to software crashes.

Google came up with the answer eventually.

Go to http://myserver/crm/eware.dll/sysadmin and click the username hyperlink for each session you want to end. It seemed to let me do this without checking any of my credentials, so I don't know how secure it is.
