36 <P><STRONG>Description</STRONG>
37 <P>The <B>kas unlock</B> command unlocks the Authentication Database entry
38 named by the <B>-name</B> argument. An entry becomes locked when
39 the user exceeds the limit on failed authentication attempts, generally by
40 providing the wrong password to either an AFS-modified login utility or the
41 <B>klog</B> command. Use the <B>kas setfields</B> command to
42 set the limit and the lockout time, and the <B>kas examine</B> command to
44 <P>To unlock all locked user accounts at once, shutdown the
45 <B>kaserver</B> process on every database server machine, and remove the
46 <B>/usr/afs/local/kaauxdb</B> file from each one. The
47 <B>kaserver</B> process recreates the file as it restarts.
