ACLs Maintenance

Access Control Lists (ACLs) are an extension the standard UNIX file permissions. If you have attempted to provide database protection through the use of UNIX file permissions you will have experienced the limitation that each file may have only one owner and one owning group with all other users receiving what is called the “other” category of access rights.

UNIX provides three “permissions” with regard to a file. These are permission to read, write and execute. Read and write permissions are obvious but permission to execute applies to UNIX scripts and programs. Additionally, permission to execute allows the use of a directory in a pathname. For example, if the user wished to “cd” (change directories) to a path such as /data1/subdir/mydirectory. The user could not use this pathname if he did not have “x” rights to subdir.

Access Control Lists augment the standard UNIX file permissions by allowing more than one “owner” and more than one “owning group”. With ACLs you can create a list of users and a list of groups in addition to the owner and the owning group (i.e. UID and GID) for each file and directory. Each user and each group is assigned file permissions to allow or deny read, write and execute privileges. ACLs are unique to the file for which they were created. There are not defaults (as there were with ACL implementation on the Prime).

Sentry provides a data entry screen to allow you to create and modify ACLs. To access this data entry screen, invoke the second selection from the Main Menu, “2. Database Maintenance Menu”. For the Database Maintenance Menu select number four "4. File System”. Navigate to the desired file and use “FD” (file detail) to display the existing permissions for that file.
