Can't view samba shares on MacOS clients

Since last Univention updates (5.0-2 errata547) we can’t see samba shares on MacOS clients. Giving the full server share path from Finder (example: //server/share) give correct access to the share but shares are not available when we connect to //server
Is it something related to the missing vfs_fruit module for MacOS on Samba as asked here and here?
