Description Jan Christoph Ebersbach

2014-03-31 15:20:25 CEST

A partner reported that setting the UCR variable samba/wide_links to "yes" isn't sufficient.  In addition the Samba variable "unix extensions" had to be set to "no".  At the moment this requires a manual configuration in /etc/samba/local.conf.

Setting samba/wide_links should automatically disable unix extensions.

Agreed, the incompatibility between enabled wide_links and the Unix extensions is by design, there was a security advisory some years ago on that matter:
