We have setup a small cluster to test, play & learn about the protocol servers. We have setup mmuserauth for AD + RFC2307 and we can share and access data via SMB and access is on windows clients with no issues.
The file DAC of a file created via windows looks like this from the SS cesNode: $ ls -l total 0 -rwxr--r-- 1 SPECTRUMSCALE\newmanjo SPECTRUMSCALE\ces-admins 33 Nov 10 17:29 helloworld.txt The NFS protocol is also exported for NFS 3,4 and when mount using NFS version '3' from an AIX 7.1 server I see also OK DAC names uid / group, so the UID mapping is working. The AIX is linked to the AD for LDAP account services and I can query accounts and get shell logon for accounts defined within AD for unix services. # ls -l ( from AIX client NFS V3) total 0 -rwxr--r-- 1 newmanjo ces-admi 33 10 Nov 17:29 helloworld.txt Now the Problem: When I mount the AIX client as NFS4 I do no see the user/group names. I know NFS4 passes names and not UID/GID numbers so I guess this is linked. # pwd /mnt/ibm/hurss/share1 # ls -l ( from AIX client NFS V4) total 0 -rwxr--r-- 1 nobody nobody 33 10 Nov 17:29 helloworld.txt On the AIX server I have set NFS domain to virtual1.com # chnfsdom Current local domain: virtual1.com This matches the DOMAIN from the mmnfs config list domain ( not 100% sure this is correct) [root@hurss4 ~]# mmnfs config list NFS Ganesha Configuration: ========================== NFS_PROTOCOLS: 3,4 NFS_PORT: 2049 MNT_PORT: 0 NLM_PORT: 0 RQUOTA_PORT: 0 SHORT_FILE_HANDLE: FALSE LEASE_LIFETIME: 60 DOMAINNAME: VIRTUAL1.COM DELEGATIONS: Disabled Also the 'nfsrgyd' a name translation service for NFS servers and clients is running. lssrc -s nfsrgyd Subsystem Group PID Status nfsrgyd nfs 8585412 active Summary / Question: Can anybody explain why I do not see userID / Group names when viewing via a NFS4 client and ideally how to fix this.
