I am not sure if I understand you correctly.  Is this on the server or
on the clients?  Where the filesystem the home directories live on the
server should not make much difference. They are bind mounted from
wherever they are to /srv/nfs4/home to be exported.  Take a look at
/etc/fstab and /etc/exports.

Note that if you change the mount point on the clients, you have to
modify the autofs configuration in LDAP.  Take a look at
'config/files/etc/ldap/autofs.ldif/SERVER_A' for the default. To
modify that on an already installed system, you need to use ldapvi or
something like that to modify the data in LDAP.

That's good to hear!

Usually it's the other way round:  You mount the partition on where your
home directories are going to live.  Then you bind mount that
directory to '/srv/nfs4/home0' to make it available for exports,
cf. /etc/fstab:

[...]
/dev/vg_system/home     /lan/mainserver/home0   ext4    usrquota ...
[...]
/lan/mainserver/home0    /srv/nfs4/home0        none    bind    ...


Hope that helps a bit.  As I'm not sure if I go you right, please
describe your problems and modifications in more detail if I got
something wrong.

Best regards,
