1) As an AFS user defined in the pts database (without admin privileges), should I be able to see foreign cells that are mounted at /afs/foreign_cell when logged in to any client machine that mounts the AFS filesystem at /afs? I can see them when I'm logged in as such as user to the _server_ machine (also configured as a client), but not when logged in as such a user to a client-only machine. Do I have to explicitly make each foreign cell available on each client machine somehow?
In order for a cell to be accessible on any given client (including one which is also an AFS server), it normally must appear in the CellServDB on that machine. In most cases, this file is /etc/openafs/CellServDB or /usr/vice/etc/CellServDB, depending on whether your OpenAFS was built with GNU-style paths or Transarc-style paths.
The CellServDB file is processed by afsd on startup, so adding things to it after AFS is already running won't have much effect. However, you can use the 'fs newcell' command to inform the running cache manager about a new cell, or changes to the set of database servers for an existing cell.
If you start afsd with the --afsdb switch, then cells which publish AFSDB records in DNS need not appear in the CellServDB file; the cache manager will use the AFSDB records to find database servers for such cells.
So my question (2) is: is this absence of the AFS ID as seen in the output of the tokens command going to cause me any problems?
Nope. This is entirely dependent on whether whatever tool you used to set tokens bothered to store an ID. Some tools look up your ID in the pts database, some just use your unix UID, and some don't bother to set an ID at all. AFS itself doesn't use this feature; it was there entirely for the benefit of a small number of tools that thought they wanted to know what your AFS ID was. The only known tools that use this "feature" are certain components of the Andrew Message System.
