[OpenAFS] Trying to figure out how to work this

[Chris Snyder]

I'm trying to figure out how I should go about setting OpenAFS for my 
network.  Here's my network configuration:

There are two domains on this network - mvpsoft.internal and 
mvpsoft.servers.  Mvpsoft.servers is behind a NAT firewall, and 
mvpsoft.internal is behind a firewall that is on mvpsoft.servers, which 
gives it an additional level of security.  Computers on mvpsoft.internal 
are not accessible by mvpsoft.servers, but boxes on mvpsoft.servers are 
accesible from mvpsoft.internal.  Mvpsoft.servers is our DMZ, containing 
web, mail, DNS, etc. servers.

I'm going to have two AFS cells - mvpsoft.internal, and mvpsoft.servers, 
hosted on servers on the domains that match the cell names. 
Mvpsoft.internal will be primarilly for user file storage, while 
mvpsoft.servers will have some user file storage (mainly from 
telecommuters), and will also have our web server files.

I'd like to have user data synchronized between the two cells.  Is there 
an easy way to do this automatically?  My goal is to have users be able 
to use their usernames and passwords transparently from any computer on 
the network.  Is this possible?  Thanks in advance.
