Assign User Groups management of specific content

Hi Tuan,

I need to assign groups of users to access and manage specific content.

Can I use the groups created by the users of Joomla Component, or are obliged to use the application "User Ids" (ID Of users who can access to this category, comma seperated. If you enter into this field ID of users, Only these users can see and access to this category!) for each category of EDocman? Thanks
