Admin login goes to change password screen [solved]

[Phuture]

Heya!

Not sure what I did but when ever I login as admin to the web manager on my TS410 I just get taken to the change password screen. I've tried pressing the reset button for 3 seconds which reset the admin password etc however I'm still getting the same problem when I try to login. I also cant get into the configure section using the qnap finder. I think it's because the admin account no longer belongs to the administrators group? However I'm not sure how to add it back in without the web panel. I can however log in to SSH but as I'm a linux nub I'm not sure how to do it, is there a way I can add the admin account back into the administrators group via command line?

Thanks in advance!

Just had a response from Support they recommended the following action :

"You can try to restore the default setting back , there are 3 setting you can try"

/etc/default_config/shadow
/etc/default_config/password
/etc/default_config/group

To current setting

/etc/config/

I replaced the 3 items in /etc/config with the default ones and I'm back up and running

do cat /etc/group and cat /etc/passwd and it should show you the groups the admin account belongs to now.

it should give you an output like this:
admin0:0:administrators:/share/homes/admin:/bin/sh
where admin is the user, administrators the group.
It will do this for every user/group

Thanks Mark below is what I get for each of the commands. So it shows that admin is still part of the administrators group then? So I'm now completely unsure as to why I cant get into the web admin panel

[/] # cat /etc/group
# m h dom m dow cmd
