We don't do *any* of the reparse point stuff yet (no demand as I recall it's Admin only on Windows).

Just that you know: I'm trying to have home shares on the network, and sometimes users need symlinks (in some osx .apps or when installing some ruby gems). I'm using samba because it should also work with OSX.

I'm using samba because it should also work with OSX.Well there's a workaround called "Minshall/French" symlink format: https://lists.samba.org/archive/samba-technical/2014-September/102476.html that hides the symlink target inside a 'special' file. That should still work over SMB2, but it's tunnelling stuff inside the protocol, not really protocol support. It's what the Linux CIFS client uses when it has to do symlinks against a Windows server which doesnt' support the UNIX extensions.

Inferring from `git grep IO_REPARSE_TAG_SYMLINK` it seems smbclient does support it by virtue of the "symlink" command. Unfortunately I can't test against OS X SMB2 server atm, because once again I'm getting strange authenticaton errors. -Ralph -- SerNet GmbH, Bahnhofsallee 1b, 37081 G?ttingen phone: +49-551-370000-0, fax: +49-551-370000-9 AG G?ttingen, HRB 2816, GF: Dr. Johannes Loxen http://www.sernet.de,mailto:kontakt at sernet.de
