Description Nils Goroll 2008-04-15 10:54:05 UTC
(not sure if this is really a VFS Modules issue)

seen on

$ uname -a
SunOS nodename 5.11 opensol-20071112 i86pc i386 i86pc
$ /usr/sfw/sbin/smbd -V
Version 3.0.28a

  preload modules = /usr/sfw/lib/vfs/zfsacl.so.0

.. seems to trigger a segmentation fault when logging in

I have not yet invested any time in further investigation, but
I did not want to leave this undocumented.

Sorry if this report is obsolete or redundant, did not find
any bug reports containing 'preload', though.

Can provide binaries, core files and configuration, if needed.

I assume this was fixed in the meantime, please reopen if you can still see this with latest samba releases.
