I have finally managed to understand which was the problem. Every check from the troubleshooting guide was OK, so I need to "open the mind" and look better.  The problem was that in the "System" zone was missing the Active Directory provider. I have then modified the zone to use also the ADS provider and now everithying is working as expected:  IsilonTest-1# ls -ltra total 18 drwxrwx--- +  2 group  PIGI\domain users    0 Apr  5 19:12 OkShare2 drwxrwx--- +  3 group  PIGI\domain users   24 Apr  5 19:30 OkShare1 drwxrwx--- +  2 group  PIGI\domain users    0 Apr  6 09:18 home drwxrwx--- +  2 group  PIGI\domain users    0 Apr  6 09:31 MultiRightShare drwxrwx--- +  2 group  PIGI\domain users   91 Apr  6 12:55 sharedup drwxrwx--- +  7 group  PIGI\domain users  133 Apr  7 09:09 . drwxr-xr-x    3 admin  admin               27 Apr 11 09:11 ..  Thanks to all for your help ! It has been really important !! Pierluigi
Hi all,   first post here so apologize for every error I could make. I have an isilon cluster where I'm studying and I've noticed a very strange thing ( in respect to what I see on some "made by other"  isilon clusters).  When looking at files created by windows on a SMB share here is the output: IsilonTest-1# ls -l total 68 -rwxrwx--- +  1 1000006  1000008   9 Apr  9 14:46 New Text Document (2).txt -rwxrwx--- +  1 1000006  1000002  49 Apr  9 14:41 New Text Document.txt  As you can see, the UID and GID is numeric, while I have seen this in other cluster with their original names.  If I look at my authentication providers everithing seems fine, but eventually is not: IsilonTest-1# isi auth status  ID                                     Active Server     Status  ---------------------------------------------------------------- lsa-activedirectory-provider:PIGI.PRIV Pigi-AD.PIGI.PRIV online  lsa-local-provider:System              -                 active  lsa-local-provider:TestAccessZone      -                 active  lsa-local-provider:pippo               -                 active  lsa-local-provider:ThirdAccessZone     -                 active  lsa-file-provider:System               -                 active  ---------------------------------------------------------------- Total: 6 IsilonTest-1# isi auth ads view PIGI.PRIV            Name: PIGI.PRIV          Status: online  Primary Domain: PIGI.PRIV          Forest: PIGI.PRIV            Site: Default-First-Site-Name  NetBIOS Domain: PIGI        Hostname: isilontest.pigi.priv Controller Time: 2018-04-09T17:36:52 Machine Account: ISILONTEST$        Groupnet: groupnet0  I have some suspect, but would like to initially discuss about this without talking of it, just to not give false ideas .  What, in your experience, could cause such behavior ?  Thanks in advance  Pierluigi
Strange behavior on files and dir created from Windows.
