Description of problem:
 My Redhat Enterprise Linux WS 3.0 Update 7 upgraded to Update 8, then my 
autofs failed.
It seems to me that the vsion of autofs on update 8. autofs-4.1.3-186, cause 
the problem.
So all my NIS automount maps fail.

   When I start the autofs (# service autofs restart), it shows "Not 
Mountpoints Defined" even though there are a lot of mount points defined in 
NIS. Unless I put those mount points into /etc/auto_<map files>.

   Temporarily work around is roll back the autofs to autofs-4.1.3-168 which 
comes with Update 7.


Version-Release number of selected component (if applicable):
autofs-4.1.3-186

How reproducible:


Steps to Reproduce:
1. install autofs-4.1.3-186
2. create NIS map auto_master with "/home  auto_home" in it
3. Create NIS map auto_home with "user1  <NFS_server>:/users/user1"
4. Make sure <NFS_server>:/users/user1 is shared out on NFS
5. echo "+auto_master" > /etc/auto.master
6. /etc/rc.d/init.d/autofs start
  
Actual results:
# /etc/init.d/autofs start
Starting automount: No Mountpoints Defined    [  OK  ]

Expected results:
# /etc/init.d/autofs start
Starting automount:        [  OK  ]
