In smb.conf on the server I have:
unix extensions = no
wide links = yes
Now I mount my home directory. I have two files there: a.text and b.txt which is a link to "/home/zap/a.txt".
Result: The link 'b.txt' is not visible on the client, despite the "wide links" setting.
If I change b.txt to be a link to "a.txt" (no absolute path), it works fine.
