Hey Rob,
When starting idmapd or stopping it, logs on the LDAP server don't
change.  But UID and GID's change to nfsnobody when I set 
Nobody-User
and Nobody-Group to nfsnobody in /etc/idmapd.conf .

I don't know that merely restarting the service is going to spark
queries against LDAP. You'd probably need to do something to provoke
that (like doing an ls).
Nothing.  Once at restart of the host do I see something from ls 
but on
second execution of ls or any type of directory interaction, nothing
happens.  Then it repeats randomly.

Can you expand on this? What are you seeing on the client side? What
queries do you see in LDAP related to the request (any?) Remember that
the 389-ds access log is buffered so it can take up to 30 seconds for
the logs to update.

Got it.  Here is the 389-ds log at the same time as the client prints
these nfsidmap messages:

Ok I have zero experience with nfsidmap over LDAP but a few 
observations:

- Your search base is wrong. For users it should
cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM
- It is searching on a non-existent objectclass From what I can tell you
need to set
NFSv4_person_objectclass=posixaccount
NFSv4_name_attr=uid

An alternate thing to try is to set Method=sss instead of umich_ldap and
see if that helps.

rob

Thanks Rob.  But unfortunately none of those did the trick.

[General]
Verbosity = 9
Local-Realms = NIX.MY.DOM,MY.DOM
Domain = nix.my.dom
[Mapping]
[Translation]
Method = sss,umich_ldap,nsswitch,static
GSS-Methods = sss,umich_ldap,nsswitch,static
[Static]
[UMICH_SCHEMA]
LDAP_server = idmipa01.nix.my.dom
LDAP_base = cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM
LDAP_people_base = DC=NIX,DC=MY,DC=DOM
LDAP_group_base = DC=NIX,DC=MY,DC=DOM
NFSv4_person_objectclass = posixaccount
NFSv4_name_attr = uid

Well the weekend's here though so maybe I can spend a little more time 
focusing on this and finally get it solved.  The tip to use sss as the 
Method was great and I aslo added it to the GSS-Methods as well but no 
luck.  The fact that localdomain even appears in the logs bothers me.  
I don't think it should given the Domain is set correctly in the 
/etc/idmapd.conf file.


I'm using NFS Ganesha for my NFS mounts ( It's a user space version of 
NFS. )  However, they don't need the idmapd service running and load 
only the idmapd libraries.

But the default value for the Domain in the idmapd libraries is 
localdomain and perhaps that's why it keeps showing up even though I 
explicitly set the Domain = nix.my.dom  .

And perhaps that's why things don't work. Guess I'll see how all this 
works with the built in Kernel NFS module.

LDAP_server = idmipa01.nix.my.dom
LDAP_base = cn=accounts,DC=NIX,DC=MY,DC=DOM
LDAP_people_base = DC=NIX,DC=MY,DC=DOM
LDAP_group_base = DC=NIX,DC=MY,DC=DOM

The people basedn should probably be cn=users,cn=accounts,... and 
the
group base cn=groups,cn=accounts,... Unles it cleverly smashes that
together with LDAP_base, I'm not sure what it does. The 389-ds 
access
logs will tell you if it is trying at all (note the logs are
write-buffered so you won't see immediate updates).

If you have compat enabled then idmapd may be getting multiple 
entries,
one from cn=compat and one from the main tree and that could be
confusing it.
No difference.  Even the IP defined users are having this issue.

However, and this may be a very dumb question, but you raised 389-ds
logs.  I'm using IPA Server, not 389-ds unless you're implying I may
need packages?  The IPA servers come with 389-ds-base installed 
but do I
need this or something else on the IPA clients as well?

In the existing IPA logs, no other log entries corrolate with the
nfsidmapd messages on the client.

Method = umich_ldap,nsswitch,static
GSS-Methods = umich_ldap,nsswitch,static

However it still lists:

user_dn : <not-supplied>
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init:

use_ssl : no
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init:
ca_cert : <not-supplied>

and I'm not sure what variables idmapd.conf uses for password and 
user.
Still, I've left the LAB KDC open so no users and passes are 
needed for
simple lookups.

After setting the above, the messages in the logs changed slightly:

(Port 389 between client and server are open.) Seems like the line:

Mar 15 01:29:24 ipaclient01 nfsidmap[1853]: key: 0x62dd191 type: uid
value: tomk@localdomain timeout 600

might be to blame.  It's the first line that shows localdomain, 
but it
should not.  My hosts file:

[root@ipaclient01 ~]# cat /etc/hosts
127.0.0.1       localhost localhost.localdomain localhost4
localhost4.localdomain4
::1             localhost localhost.localdomain localhost6
localhost6.localdomain6
192.168.0.236   ipaclient01.nix.my.dom ipaclient01
[root@ipaclient01 ~]#

Guessing key get's it's info from /etc/hosts directly and I should 
look
at that?

Tom

Is there a way to structure /etc/idmapd.conf to allow for proper

You might be able to correlate that to the 389-ds access log to 
see
what
queries are being executed.

You probably need to set LDAP_people_base and LDAP_group_base as
well.

I think ipa-client-automount only sets the Domain value and 
doesn't
configure the ldap section at all.

Solved.

Here's the solution in case it can help someone else.

To get a certain feature in NFS Ganesha, I had to compile the V2.6 
release from source.  When configuring to compile, idmapd support got 
disabled since packages were missing:

libnfsidmap-devel-0.25-17.el7.x86_64

Installed the above package and recompiled with nfsidmap support enabled 
and this issue went away.  Users now show up properly off the NFS mount 
on clients.
