Just installed the 10-1 firmware from a clean drive using the instructions in the forums (which went without a hitch once ubuntu's foibles were figured out).
However, when I create a user, give them a password, allow full access to public and accept to save, It then takes me back to the Create New User screen with just 'dummy' listed.
If I then create a new share, give it a name say 'test' then want to add Users, only 'dummy' is available. If I then say no access to dummy, the screen goes back to the Create New Share screen and just public is shown.
Then, selecting create new share and entering test as the share name and dummy no access, it says at the top 'could not add share, share name already exists', then under users, shows all users that have been created on the unit, that were not showing up under the actual users section.
This also makes it a bit of a problem as you cannot delete/update users or the shares as they are just not shown anywhere.
Now, if you then go in to the System Management | Information | View system information, it shows up the users that you have added along with their passwords.
After adding lots of shares and lots of users to try and figure out how to get it to work first time, its seemed to sort itself out so when clicking User Account or File Share menu's, its lists it all as expected. Maybe this was a bit of a fluke?
