Symptoms

Customer has NFSv4 ACLs are similarly defined for SAMFS filesystem directories, prod and test. These directories are configured as Samba shares on a Windows 7 workstation.

The customer's user name is a valid user in group@. He is not the owner of the file. He can access file Copy1 in Windows folder named test. But, he cannot access file copy1 in Windows folder, prod.
  
Samba log shows error like this when accessing a shared file in the production environment:

[2015/05/11 11:35:48.654049, 0] smbd/uid.c:271(change_to_user_internal)
PANIC: assert failed at smbd/uid.c(271): conn->force_group_gid != (gid_t)-1


If he makes himself the owner of the file copy1, he can access copy1 without a problem.

The customer was able to access copy1 after he remotely logged in to the Windows server.

He was also able to access copy1 after he rebooted the Windows server and logged in to the samba share.

Changes

Setting up permissions using NFv4 ACLs for multiple groups and users accessing the samba share folders
