[OpenAFS] butc authentication in multiple cells?

[Karsten Thygesen]

Hi

We have two different cells deployed, and we would like to share a
common backup server (with different tapedrives for each cell). 

Currently, that backup servers have a local keyfile and runs with
"butc -localauth" and that works just fine, but how do we add the
other cell? As far as I can see, there is no way to store keys from
different cells in the KeyFile, so how do we handle authentication of
the butc process for the other cell?

Any ideas?
