Security on UNIX FrontPage relies on access files to add FrontPage-extended web administrators, authors, and browsers (site visitors) with the proper permissions to the Web server's account list, and to protect content and programs in FrontPage-extended webs. FrontPage creates a directory named _vti_pvt for the root web and for each subweb. In each FrontPage-extended web with unique permissions, the _vti_pvt directory contains the following two files:
On Netscape servers, there are no service.pwd or service.grp files. The Netscape password files are:
An access file in the _vti_bin directory controls access to the browse-time FrontPage program, shtml.exe. If all users have browse permission, this is set in the access file. Otherwise, the access file points to a list of users and groups with browse access. A separate access file in the _vti_adm directory sets POST permissions for the administrative program, admin.exe. A third access file in the _vti_aut directory sets the POST permissions on the authoring program, author.exe. When you use the Permissions or Security command in the FrontPage client to give a user browse access to a FrontPage-extended web, the user is given an account on the Web server. This is done by adding the user's name and password to the single service.pwd file (or, on Netscape servers, users.pwd) pointed to from the _vti_bin directory's access file. Also, when an IP address restriction is set on browse access to a FrontPage-extended web, this restriction is added to the _vti_bin directory's access file. When you give a user authoring access to a FrontPage-extended web, the user is given an account on the Web server. This is done by adding the user's name and password to the service.pwd file and to the Authors group in the service.grp file pointed to from the access files stored in the _vti_bin and _vti_aut directories. This enables the user to send HTTP POST requests to author.exe and use the browse-time program, shtml.exe. (On Netscape servers, the process is similar.) When you give a user administrative access to a FrontPage-extended web, the user is given an account on the Web server. This is done by adding the user's name and password to the service.pwd file and to the Administrators group in the service.grp file pointed to from the access files stored in the _vti_bin , _vti_aut, and _vti_adm directories. This enables the user to send HTTP POST requests to admin.exe, author.exe, and shtml.exe. (On Netscape servers, the process is similar.) The set of access files for a FrontPage-extended web is illustrated in the following two tables.
