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?
