Tried connecting to Cortland to run Contribute from it, but was unable to authenticate using existing afp shortcut on my mac, using sarneil and root. Checked Cortland to ensure sarneil was an admin user, changed the password for sarneil on that machine and tried again. Still no luck. Also tried connecting using afp and the ip address - same result. Greg able to log in from his computer as gregster. Not sure what the problem is or how to resolve it. Will restart both computers tomorrow morning and try again.
