I can fix locally before pushing and one packaging question. I'll ask
those inline when replying to the patches themselves.
But more importantly, I have a question on testing the patches. I admit
my NFS internals knowledge is quite lacking, so maybe these are basic
questions..how exactly do I make sure the plugin mapping functions are
called? I tried attaching gdb to rpc.idmapd and doing various operations
to the file (ls, echo "foo" >> file) etc but still no luck. Disabling
the sss nsswitch plugin just yields UIDs and GIDs on the client (which
is
For my test, I configured a server and a client. I can mount the shares
just fine, I see I'm using NFSv4 in the mount(8) output. I can see the
sss plugin was loaded, because journalctl -u nfs-idmap.service says:
Jul 14 12:01:21 master.ipa.example.com rpc.idmapd[24320]: rpc.idmapd:
sss_nfs_init: use memcache: 1
Jul 14 12:01:21 master.ipa.example.com rpc.idmapd[24320]: rpc.idmapd:
libnfsidmap: loaded plugin /lib64/libnfsidmap/sss_nfs.so for method
sss_nfs
My idmapd.conf file looks quite simple:
--------------------
[General]
Verbosity = 2
Domain = ipa.example.com
[Mapping]
Nobody-User = nfsnobody
Nobody-Group = nfsnobody
[Translation]
Method = sss_nfs
[Static]
[UMICH_SCHEMA]
--------------------
I guess I could also ask -- where does the rpc.idmapd daemon hook into
the system? When exactly are the translation functions called?
Thank you for your help.
