You need to change the following configuration in the GUI:
System ›› Users:User List -> Click in the admin username link
Then change the configuration in Terminal Access to Advanced Shell.
You always can restore a locked account using the Unlock button.
yes, thats it,
Try logging into the device with root and then you can change the pw.
able to login GUI as admin account, but not SSH login as admin.
already change the password through GUI, but still no luck
it turned out , user/console setting was messed up somehow.
The default configuration deny admin access to console and ssh!
The admin user is only allowed to access webui.
