Hello List! Currently I am facing the following problem. At work site we have an IBM mainframe (i6OS). We are using this mainframe as NFS server to share data between both worlds. Since the mainframe NFS supports v.4 we are using it because it is much easier to handle through firewalls (single port etc.)
In this setup the Debian server (Lenny) is acting as NFS client that is working quite cool. No problem on mounting, reading, writing files.... If I am using a fresh Squeeze installation, it is impossible to mount the NFS share. No chance. The NFS client gave me the information "Access denied". In /var/log/syslog I got the message that user xyz@domain is not mappable to a local user. I've read a lot about the domain thing from NFSv4 and also about idmapd etc.... (and tried a lot) but why it works with Lenny but not with Squeeze? This setup runs inside a VMWare Esxi environment so its easy to test the behavior. When I shutdown the Squeeze box and startup the Lenny box (same IP etc...), all is working without problems. The other way - no chance. I also read about some problems in the Debian bug tracker and a common workaround for some problems is to downgrade to the Lenny version of nfs-common, like bug #585085. My question: is anyone using Lenny and Squeeze as NFS v4 only client in parallel? I have not installed a "normal" NFSv4 server until know.... I hope anyone could give me a hint to solve this. For your information, both servers, Lenny and Squeeze are installed from scratch (net-installer) without any modifications afterwards. First thing I've tested after installation is to mount the NFS server share. I guess there has something changed in the nfs-common package because I have the same problem if I am using an Ubuntu 10.4. Should I file a bug with detailed informations? Any help is appreciated!
