Mail got posted before I was finished sorry.

I found one clue to the issue after increasing autofs logging to debug and as i 
thought it has to do with id-mapping.

Nfsidmap[1696]: nss_getpwnam: name 'adt...@ad.home@linux.home,' does not map 
into domain 'linux.home,'

Yes Client is default RHEL 7 and both IPA and NFS Server is aswell. = AD Server
share.linux.home = NFS Server
ipa.linux.home = IPA Server
client.linux.home = Client

NFS with automounted krb5p Home Directories work for IPA users.


id adt...@ad.home<mailto:adt...@ad.home>

getent passwd adt...@ad.home<mailto:adt...@ad.home>

Home Directory gets mounted by autofs through sssd but user:group is both 

The Client's sssd.conf:


cache_credentials = True
krb5_store_password_if_offline = True
ipa_domain = linux.home
id_provider = ipa
auth_provider = ipa
access_provider = ipa
ipa_hostname = client.linux.home
chpass_provider = ipa
ipa_dyndns_update = True
ipa_server = _srv_, ipa.linux.home
ldap_tls_cacert = /etc/ipa/ca.crt
autofs_provider = ipa
ipa_automount_location = default
subdomains_provider = ipa
services = nss, pam, autofs, ssh
config_file_version = 2

domains = linux.home

I have found one problem when using a NFS 4 shared Home Directory for AD users 
logging in to IPA.
I have created a NFS share /home/ and use autofs map in IPA.
All wbinfo tests works as well as id.
I can login fine through SSH and Shell with<>
The problem is that I can add the AD user as owner of his Home Directory and if 
I log in to the NFS Server locally or through ssh permissions are correct but 
when logging in to any other computer i get "nobody" as owner.
Are those computers RHEL7 NFS clients with SSSD?
Can you describe them in more details please?

Groups are no problem since AD groups can be mapped to Posix groups.

Idmap.conf domain is set to the IPA Domain.

Is there some way to get NFS working with the AD user as owner of his Home 

Thanks for any help.
