Chapter 9 Access Control Lists 9-3
...with the result that all users have read permission. For example, with only read
permission for a Sun MediaCenter server, a user can look up titles on the server, but
cannot play a stream.
Each instance of the ServerAcl file must contain a line that indicates the version
number of the file; this line must be the first uncommented line in the file. The
format of the version line is:
Version <number>
If the version line is missing or incorrectly formatted, or has an unsupported version
number, the MSM produces warning messages but continues to parse ServerAcl.
9.4 Player ACL
There is no file for player ACLs. When you create a player (using
msmPlayerLookup()), you, the creator, have full permissions—read, control, and
admin—for that player. You change permissions by assigning one of a set of access
levels to the MsmAccessList structure. Permissions are assigned to a specific user.
TABLE 9-2 shows the permissions that you can specify:
Following creation of a player, the MSM consults the player's ACL before checking
ServerAcl.
