Permissions issue with File maker PRo v10

[Sainyam]

Hi Support,

I want to set Full access permissions for few management users and read only to all other.

I have followed the link below to create new user and assigned privilege to read only. Before creating user I have set admin password as well.

http://help.filemaker.com/app/answers/detail/a_id/5845/~/creating-and-managing-accounts-in-filemaker-pro

Now this user set as default for all users automatically, that is good in one part for me.

Now on management users I try to open that DB with Shift key and it ask for the user name and password, as I enter Admin details, shows error that the user name password you entered does not have access to the file.

that is weird..

I created new admin account but I get same error.

Can anyone please provide me step by step instructions how I can apply read only on few users and on other admin rights, Guest account should not be used for security purpose.
