I agree entirely with toomas’ sentiment vis-a-vis “it is not as simple as it appears”, with the qualifier that in the case of a desired setup that is Workgroup only / no AD/ no Windows Domain, the Oracle documentation and all the relevant OI and illumos documentation I could find seemed to suggest that “it should just work” after setting sharesmb property.

**With this addition to pam.conf, it would** , and I advocate strongly for its inclusion in the base installation. (Strictly speaking, the step 3, mDNS/avahi) is not necessary to connect, only to browse)

Kind regards
