[OpenAFS] Only db server host can log into a "remote" fileserver
Sun, 01 Mar 2009 14:38:50 -0500
Upon consultation and recommendation of the fine folks on #openafs, I
ended up downgrading the second file server to 1.4.8, it now works.
For the record this was not a network issue as it was a local subnet,
with no firewalls or local ACL's involved, but something to do with
the 1.5.57 build I created for sparc_linux26.
