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.
From /var/log/messages:
Nfsidmap[1696]: nss_getpwnam: name '[email protected]@linux.home,' does not map
into domain 'linux.home,'
Are you sure the message is exactly like this, with a comma after linux.home?
The reason I'm asking is because the code that prints the message looks
like this:
localname = strip_domain(name, domain);
IDMAP_LOG(4, ("nss_getpwnam: name '%s' domain '%s': "
"resulting localname '%s'\n", name, domain, localname));
if (localname == NULL) {
IDMAP_LOG(0, ("nss_getpwnam: name '%s' does not map "
"into domain '%s'\n", name,
domain ? domain : "<not-provided>"));
goto err_free_buf;
}
note that it doesn't have comma anywhere in the string printed.
Can you please increase the log level to 4 so that we can see the first
string (nss_getpwnam: name '....' domain '...': resulting localname
...)? it would be

Yes Client is default RHEL 7 and both IPA and NFS Server is aswell.
server.ad.home = 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.

Hi,
Environment:
RHEL 7 IPA Server 3.3 with a trust to a Windows 2012 Server AD
RHEL 7 NFS Server
RHEL 7 Client
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/adexample.org and use autofs map in IPA.
All wbinfo tests works as well as id.
I can login fine through SSH and Shell with
[email protected]<mailto:[email protected]>
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
Directory?
Thanks for any help.
