Q: On Centrestack server, you may see local users like glad1_<user>/g_<user>/g1_<user>. What's the users for?
A: Windows has a limitation. Under one user's session, can not access a SMB file share as multiple users.
On Centrestack, when attach a share directly, with "Always access the storage using the logged in user's identity", each time an AD user accesses the team folder, Centrestack needs to access the share as the user.
. If Centrstack is on the same domain as the share, it can impersonate as the AD user and access the share. Here, no need to create the dummy g_ user/g1_user.
. If Centrestack is not on the domain as the share, it can not impersonate as the AD user. In this case, due to the windows limit, Centrestack cannot access as the AD user directly. It will prevent other AD users to access the share.
As a workaround, Centrestack creates a dummy user like g_user/g1_user. A session as the dummy user is created. Centrestack will use the dummy user's session, to host the CIFS share connection for the AD user. The real connection to the share is still as the AD user.
