What is A.C.L.?

Mosaic allows users to give others access to their files by changing ACLs (Access Control Lists) for directories. This can be done through Windows XP Explorer or the AFS ACL Tool. If you are unfamiliar with ACLs, please see the FAQ or the links below for more information.

NOTE: There is a maximum limit of twenty (20) ACL entries (individual user IDs or pts groups) for a directory.

If you anticipate needing to have more than 20 entries for a directory or will be giving the same set of users permissions in multiple directories or anticipate adding or deleting users with the same access rights for the same directories from time to time you should consider using "groups". A group is a collection of individual user IDs referred to by a single name for the entire collection and for which access rights may be assigned or changed using the group name rather than the individual names. Currently the native Windows XP method of setting ACLs does not support creating groups and you must use the "AFS ACL Tool" or the "pts" commands in the Unix/Linux environment following the instructions and examples outlined here.
