[CentOS] autofs with nfs plus local directories

Hi,

I have a autofs configured to mount home dir from NFS. All user
accounts lookup is done using LDAP. All is working fine with this
setup. Now I need to create a local user account and have its home dir
also on local system. So I added a new user account and changed
auto.home as follows:

test1         -rw,hard,intr   /home/test1
*             -rw,hard,intr   nfs1:/export/users/&

But this stuff is not working. If I change test1 user's home dir to
'/opt/test1', it works fine. Log messages indicate:
'umount_autofs_indirect: ask umount returned busy /home'. I have some
LDAP users logged on to system. Do I need to tell them to logout to
successfully reload autofs? Any clues on this would be really helpful.

Thanks,
CS.
