Is there a utility that can convert the DES passwords so that they're 
encrypted using md5?

Also, the super user seems to be able to figure out the usernames for maching 
IDs. For example, when i do a directory listing, I see all the ownerships 
properly. However, when I su into another user, I get the following message 

id: cannot find name for the user ID ****

Also a directory listing shows the userid instead of the username for 
file/directory ownerships.

Any ideas?
