Hi Dale,

the funny thing: I have the same problem with Bullseye 64-bit 
4.17.3+dfsg-1 & dfsg-2 and shares rights over groups. If I set the 
rights direct to the user, it works.

And now the really funny thing: One user is working again and I'm not 
really sure why.

Waiting for dfsg-2 in the hope this might solve the problem I used the 
time to change or add some groups for my NAS devices and it seems till 
then the user is working again. He got most of the new groups.

I've tested the join, I've got on each device "Join is ok". It's really
