UNC Linux Users Group

[Gary Bishop <gb AT cs.unc.edu>]

Our AFS systems here in CS only give me a token if I login with a 
password, something I don't ordinarily do. I found that adding the 
argument "-o PreferredAuthentications=password" to the command line gets 
it to prompt me properly.

I also found the "-o idmap=user" option useful to get user ids mapped 
properly.
