<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>kaserver.DB0</B> file contains the Authentication
|
||
|
|
Database, which records server encryption keys and an encrypted form of all
|
||
|
|
user passwords. The Authentication Server (<B>kaserver</B> process)
|
||
|
|
uses the information in the database to enable secured communications between
|
||
|
|
AFS server and client processes.
|
||
|
|
<P>The <B>kaserver.DBSYS1</B> file is a log file in which the
|
||
|
|
Authentication Server logs each database operation before performing
|
||
|
|
it. When an operation is interrupted, the Authentication Server replays
|
||
|
|
the log to complete the operation.
|
||
|
|
<P>Both files are in binary format and reside in the <B>/usr/afs/db</B>
|
||
|
|
directory on each of the cell's database server machines. When the
|
||
|
|
Authentication Server starts or restarts on a given machine, it establishes a
|
||
|
|
connection with its peers and verifies that its copy of the database matches
|
||
|
|
the copy on the other database server machines. If not, the
|
||
|
|
Authentication Servers call on AFS's distributed database technology,
|
||
|
|
Ubik, to distribute to all of the machines the copy of the database with the
|
||
|
|
highest version number.
|
||
|
|
<P>Always use the commands in the <B>kas</B> suite to administer the
|
||
|
|
Authentication Database. It is advisable to create an archive copy of
|
||
|
|
the database on a regular basis, using a tool such as the UNIX <B>tar</B>
|
||
|
|
command.
