Can you please provide more details?

When you say "add a user on the server", do you mean with e.g. useradd, or changing the ACLs on the share, or ?

Can you reliably reproduce this every time?

What do you mean by "crashes the Windows 8 client"? Does the CIFS mount fail? Does the machine die with a kernel panic and reboot?

Hello Rich,

Sorry I should have been more specific, I've put more time to test this one.

So basically what happens is: On the ZFS server (let's call it ZFSSERVER) running native CIFS share, I have the following accounts:

root (default)
User1 (local solaris user)
User2 (local solaris user)
Group1 (contain User1 & User2, local solaris group)

The default permission on a CIFS share is root (full perm.), and everyone

On a Windows 8 machine, by authenticating as root, I can go and edit security permission on the share.

I can successfully add a ZFSSERVER\\User1 and ZFSSERVER\\User2 and give them some permission.

However I found out that it's adding the group that cause the crash,

In windows 8, going on properties on the share, then Security Tab, then edit, then add, then advanced, then Find Now,

It list all the Users group and default built in group there,
the important one is ZFSSERVER\\Group1

If I select that group and click OK, explorer.exe crash (explorer.exe is the process that display any window open, as well as taskbar) windows then restart it automatically.

In the event viewer I have this:

Faulting application name: Explorer.EXE, version: 6.2.9200.16433, time stamp: 0x50763312
