Correct. There is an issue in NFS client utilities called by the kernel
to handle credentials via upcall interface that they cannot yet handle
kernel keyring-based ccaches.

Subject: [Freeipa-users] krb5 and nfsv4 not working right

Hi guys,

I've followed every guide I can find on this subject. What I'm trying to is to 
get our home directories which are shared via NFS from the FreeIPA server 
mounted via autofs on the clients.

The client is kact-man-001 and the FreeIPA server is kact-adm-001

/etc/exports:


I've done the ipa-client-install and the ipa-client-automount

However, when I log in, my homedir is mounted as expected but what I get in the 
messages log is:

Nov 15 12:52:25 kact-man-001 gssproxy: gssproxy[770]: (OID: { 1 2 840
113554 1 2 2 }) Unspecified GSS failure.  Minor code may provide more 
information, No credentials cache found

A lot!

/etc/krb5.conf is default from the FreeIPA installation:

  default_ccache_name = KEYRING:persistent:%{uid}


The autofs setup looks like this:

---------------------------------------------------------

[root@kact-adm-001 log]# ipa automountmap-find
Location: default
------------------------
3 automount maps matched
------------------------
  Map: auto.direct

  Map: auto.home

  Map: auto.master
----------------------------
Number of entries returned 3
----------------------------
[root@kact-adm-001 log]#



[root@kact-adm-001 log]# ipa automountkey-find
Location: default
Map: auto.home
-----------------------
1 automount key matched
-----------------------
  Key: *
  Mount information: -fstype=nfs4,rw,sec=krb5,rsize=8192,wsize=8192
kact-adm-001.kact.sblokalnet:/data/home/&
----------------------------
Number of entries returned 1
----------------------------
[root@kact-adm-001 log]#

---------------------------------------------------------

Now, the BAD thing is, trying to copy a large file to the automounted dir on 
the client just hangs:

[tba@pc588 images]$ scp NAS4Free-x64-LiveUSB-10.3.0.3.2987.img.gz
tba...@kact-man-001.kact.sblokalnet:.
tba...@kact-man-001.kact.sblokalnet's password:
NAS4Free-x64-LiveUSB-10.3.0.3.2987.img.gz
                                           100%  281MB  93.6MB/s
00:03
[hangs]

And my logged in session on the client hangs if I try to do ls in my
homedir:
[tba@pc588 ~]$ ssh tba...@kact-man-001.kact.sblokalnet
tba...@kact-man-001.kact.sblokalnet's password:
Last login: Tue Nov 15 13:07:12 2016 from pc588.sb.statsbiblioteket.dk -sh-4.2$ 
-sh-4.2$ -sh-4.2$ pwd /home/tba-sb -sh-4.2$ hostname
kact-man-001
-sh-4.2$
-sh-4.2$ ls
[hangs]


And I see a huge amount of the GSS failures in the messages file on the
client.


Any suggestions?

TIA
