Hello, Found another problem related to idmapping, I think. One of our users reported chgrp had stopped working (under 3.4.44, coming from 3.2.11). I reproduced it under krb5i (I can send the cap if necessary). The SETATTR call is failing because it is not using the domain as set in idmapd.conf, but the domain of the host instead. So, for example, our domain is csupomona.edu. Trying to run "chgrp csupomona testfile" should set the group to csupomona@xxxxxxxxxxxxx, but the NFS layer is sending csupomona@xxxxxxxxxxxxxxxxx (the subdomain of the host). The idmapper seems to know what's going on, as the -vvv output produces: nfsidmap[3598]: key: 0x3df841e type: group value: 17730 timeout 600 nfsidmap[3598]: libnfsidmap: using domain: csupomona.edu nfsidmap[3598]: libnfsidmap: loaded plugin /usr/lib64/libnfsidmap/nsswitch.so for method nsswitch Am I missing some simple host configuration or is this a deeper issue? -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
