Hello! I have updated my Debian 11 with the Linux 6.8.2 kernel, running rpc.nfsd with various NFSV4 clients. Userland stayed exactly the same, so neither idmapd or nfs-utils were changed. But I now see lots of weird group names (not usernames, they are normal) from idmapd, but not all group name mappings are affected: Mar 28 19:15:18 ingramnode86 rpc.idmapd[400]: nfsdcb: authbuf=*,10.2.66.30 authtype=group Mar 28 19:15:18 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: calling nsswitch->name_to_gid Mar 28 19:15:18 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: nsswitch->name_to_gid returned -22 Mar 28 19:15:18 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: final return value is -22 Mar 28 19:15:18 ingramnode86 rpc.idmapd[400]: Server : (group) name "^PM-!M-?M-4q" -> id "65534" Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfsdcb: authbuf=*,10.2.66.30 authtype=group Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: calling nsswitch->name_to_gid Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: nsswitch->name_to_gid returned -22 Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: final return value is -22 Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: Server : (group) name "PM-^^M-^OM-4q" -> id "65534" Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfsdcb: authbuf=*,10.2.66.30 authtype=group Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: calling nsswitch->name_to_gid Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: nsswitch->name_to_gid returned -22 Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: final return value is -22 Mar 28 19:15:19 ingramnode86 rpc.idmapd[400]: Server : (group) name "M-^PM-^]/M-4q" -> id "65534" Mar 28 19:15:20 ingramnode86 rpc.idmapd[400]: nfsdcb: authbuf=*,10.2.66.30 authtype=group Mar 28 19:15:20 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: calling nsswitch->name_to_gid Mar 28 19:15:20 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: nsswitch->name_to_gid returned -22 Mar 28 19:15:20 ingramnode86 rpc.idmapd[400]: nfs4_name_to_gid: final return value is -22 Mar 28 19:15:20 ingramnode86 rpc.idmapd[400]: Server : (group) name "M- M- M-^_M-4q" -> id "65534" , Dan -- Dan Shelton - Cluster Specialist Win/Lin/Bsd
