In that case it doesn't sound like the app is trying to set Unix security. Yes, the filer maps the UID to a SID, but as described in the FAQ, you can't set Unix security in an NTFS qtree no matter what NT user you map to.

Assuming you've unsuccessfully tried to use the security troubleshooter to diagnose this, open a case with Netapp and get them a packet trace, along with the exact permissions of the files in question and the "wcc -dvv" output. Alternatively, if it is a standard application, give them a full description of how to reproduce this.

But if I change the folder permissions to full control I can then save a file from a 3rd party Unix/Solaris application. Also doesn't the filer map a user's UID and GID to a SID.

See the security troubleshooter FAQ:

http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/faq....

"I tried to 'gunzip' (un-tar, check out, etc.) a file in an NTFS qtree and it failed! Why?

"Any attempts to set UNIX security will fail in an NTFS qtree. Some UNIX applications fail to operate properly if they cannot set security. If you need to run such applications you must use a Mixed or UNIX qtree. In some cases Win32 versions of these commands are available (for example, with the cygwin tools or MKS Toolkit), which allows them to be run from CIFS clients in NTFS qtrees."

Our configuration is 760 running 6.1R1

When I try to save a file from a Unix/Solaris application to a ntfs qtree/directory I get access denied. Using an xterm I can access the directory as myself and rm, touch, vi any file, just cant do the same form a Solaris application ie...file manager and 3rd party Unix apps. I have checked the group perms, and wcc -s and -u also wcc-d and all seem ok. Has anyone seen this problem before?
