UnityVSA Community Edition - Users and groups on standalone NAS server

Hello all,

after now being able to manage local users on the standalone NAS server on an UnityVSA (see https://community.emc.com/thread/233322) I found out that I can't assign users to groups. When I want to add a new local user to an existing local group, i. e. Administrators, I get a login dialogue. After putting in the credentials of the administrator account the group can't be found. In the advanced search dialogue I get the error message that it isn't possible to open a second connection with the same credentials. I can also escape from the login dialogue. Then the advanced search dialogue shows the message that the acces is denied. These error messages are only viewable when changing the search parameters to groups or users.

I don't want to work with local accounts for the file access rights. I want to use local groups to manage the access rights without the long process of enumerating all the files and folders after every change of the access rights.

I'm using the Computer Management console of a Windows 10 Professional client to manage the NAS server on the UnityVSA Community Edition. I think there's an issue with the security context again when assigning local users to local groups. Do you have an idea how to solve this?

Thank you.
