name convention of local and global groups

I need some ideas for a naming sheme of groups in a multi domain environment.
There are local groups with NTFS permissions that contain global groups with the suiting users.

It isn´t a typical question but I need some experience "from the field".

How are the names of groups in your domains choosen?

We have two lans over a wan.  There are 5 teams on both.  We have set it up so all permissions, except in a few cases, are done at the group level.  We usually name the groups in accordance with their function or purpose (eg: accounting or secretaries, etc).  If people need access to both domains, we usually add and extension onto the group name so it is similar to the associated group that is on the local domain (eg: license and license_all or license_heads).  If you need more info or have other questions, please let me know.

how do differ between local and global or read only and read/write rights?
Do you mean local as far as the local group or local workstation?.  Set up sharing and permissions on each directory that is associated with each group.

Generally, your global groups group users according to their roles: Accountants, Managers, Sales Reps, so the name should follow that.

Local groups deal with level of access to resources: Printer Operators, DB Update.

The multi-domain nature isn't really a problem, since global groups imported from another domain will be preceded by the domain name.
I have multiple Domains spread out across the Southeast. An easy way for me to identify a machine as to where it is and who is on it is by using the first 3 letters of the machine name to corresspond to the location.

Ex. Atlanta - ATL_xxxxxxx
the x's being the last name of the user.

Groups I'll name by location/department.
This works good for me because you can add Global groups to Local groups but not vice-versa. Local groups I'll name by sever/resource.

My user names reflect both the domain they reside in as well as part of the name.

I´m looking for a nice way to include the permissions as far as possible in the group name
I would use the Standard Win NT ACL abbreviations appended to a groupname. ie  database-RW. This should give you an exact match between NT definitions and your group settings. It also is relatively short.
