Of course, because a manual mount expects a directory to already exist to mount
on. Automounter creates virtual mount points on demand and so if there are
existing directories already in place it will fail.

Stop autofs.  Move the /home out of the way.  Start automounter and than do an
ls /home.  It should "just work"

autofs works just fine with an existing directory.  It worked fine in
EL4/5/6/7.

Indeed the default config has /misc managed by automount, and that directory
exists.

No?

I use krb5 NFS with EL7 just fine on /home with autofs.

jh

ok, I have moved home out of the way and restarted automounter..
and now I see the /home directory appear when autofs is started, but 
there is still nothing there..

[root at server2 home]# cd /home
[root at server2 home]# ls
[root at server2 home]# cd jason
-bash: cd: jason: No such file or directory
[root at server2 home]# df -h ./
Filesystem      Size  Used Avail Use% Mounted on
/etc/auto.home     0     0     0    - /home
[root at server2 home]#

I still dont see any errors  in the logs on either server.

btw, my uid on both servers is the same.
[root at server2 ~]# id jason
uid=1000(jason) gid=1000(jason) groups=1000(jason),10(wheel)

[root at server1 log]# id jason
uid=1000(jason) gid=1000(jason) groups=1000(jason),10(wheel)

Does "automount -m" show what you expect?

When in doubt, enable DEBUG logging in /etc/sysconfig/autofs, as it's very
verbose about what it's doing if only you ask.
