[Samba] 4.13 -> 4.16: cannot see shares

[Andrea Venturoli]

Hello.

Yesterday I upgraded a AD member filserver from 4.13 to 4.16: this I've 
done several times without troubles, but in this particular case it 
didn't go so well.

In fact now clients cannot enumerate shares: when an user connects to 
\\fileserver, he either sees an empty folder or only his home (in a non 
deterministic way).
Other shares can be normally accessed by explicitly typing them; i.e. 
\\fileserver\share1 works properly.
This can also be tested with "smbclient -L //fileserver".

testparm shows no warnings and there's also no error in the logs.

Any hint?

  bye & Thanks
