nfs / idmap mount problem
Hi!
I've got a problem mounting NFS shares: after mounting the nfs
directory (share) it is empty, and is owned by a rather strange UID
4294967294 (on the server, also on other clients). Mounting the same
share on another box works quite well (dir is filled and owned by the
correct uid).
I suspect that is has something to do with idmap or nss/ldap however
i've no idea how to debug this further as I do not get any error or
warning messages in the console or syslog
I already increased the verbosity to 5 idmap.conf. This however does
not point out anything useful to me - you can see it in the following
excerpt of my syslog.
Setting the Domain = ... in idmap does not help, also explicitly
enabling NEED_IDMAPD=yes in /etc/default/nfs-common. The server is
running Debian 7.x the client v. 8.x
Do you have suggestions how to solve this problem or at least how to
debug it further?
Cheers Sigmund
