- This new version of the DFS_AUTH code was donated by Karsten Muuss
- <muuss@or.uni-bonn.de>. It fixes the following problems with the
- old code :
-
- - Server credentials may expire
- - Client credential cache files have wrong owner
- - purge_context() function is called with invalid argument
-
- This new code was modified to ensure that on exit the uid/gid is
- still root, and the original directory is restored. JRA.
