Set the primary group for each user to the group that is sharing the instance of the group Installation Manager. If the primary group is not set, the user must run chgrp to change the group associated with the user’s installed files.
In group mode, Installation Manager changes the umask value for the user to 002 when the umask value is 0n0 and n is an octal value. The umask value is set only for the current session of Installation Manager and does not persist after the user exits Installation Manager. The umask values are logged in the log file. Files that are created by Installation Manager have group write permissions by default. When Installation Manager starts, the group ID for the user must be the same as the group ID for group mode. If the group IDs do not match, the user cannot start Installation Manager. The rest of this topic does not apply to version 1.5.2.
The information in this section applies to versions 1.5 and 1.5.1.
Permissions can be set by the system administrator or by a group member. An administrator can set permissions for all users or each user can set permissions individually.
chmod -R g=u
This command sets the permissions of the containing directories and files such that the group permissions are equal to owner permissionsOne method for setting permissions is to set the user mask for the group. The options for setting the user mask are outlined in the Procedure section. Setting the user mask is the most efficient method for managing user permissions.
For example, user1 installs a package. User2 opens Installation Manager to modify a different package. User2 does not have access to Installation Manager files created by user1 because the change mode command was not run before user2 started Installation Manager. User2 receives a permission denied error.

To set permissions through a user mask, do one of the following tasks:
