today we had the same issue again and had to run "net cache flush" 
again. The admin there googled this:

https://community.spiceworks.com/topic/1997592-winbind-samba-some-users-unable-to-authenticate-until-local-cache-is-cleared

but a cronjob like that doesn't look like a good solution to me, more 
like a hack until a real fix is found.

Does anyone know if this issue would be solved by upgrading the DM to 
4.6.12 or even 4.7.x ?

We are unsure which way to go here.
