Access control list group pairs are used to grant privileges on the Unix Web server. One ACL is the "owner" group and has authority to alter membership in the second "authoring" ACL. There is a standard convention for creating and naming these groups.

Author groups start with g-www:g- and end in something that uniquely identifies the group with the relevant Web space. The owner group starts with g-www:owner-g- and ends the same as the authoring group. For example, the authoring ACL for the Accelerator Department Web space is named g-www:g-ad and the owner ACL is g-www:owner-g-ad.

When new Web space is set up on the Unix Web server, groups are created and applied to the space. Once the space is established, members of the owner group can make changes to authoring group.

For permissions on the Windows servers, the Web Information Manager needs to know who (the Windows account name) will be advanced author or authors in the space. On the Windows servers, administration of the Web site is restricted to the Web Information Manager and the server administrators. A global SLAC Windows security group is usually established to include the authors for the Web space. Changes to this group are made by the group owners through the HelpTrack system (see Request change in Windows Security Group).

Files on the Windows web servers can be accessed through the Windows file system or through FrontPage. See Accessing web file space on our Windows web servers for more information.
