5.5. Groups and Group Security
Groups allow the administrator to isolate bugs or products that should only be seen by certain people. The association between products and groups is controlled from the product edit page under "Edit Group Controls."
If the makeproductgroups param is on, a new group will be automatically created for every new product.
On the product edit page, there is a page to edit the "Group Controls" for a product and determine which groups are applicable, default, and mandatory for each product as well as controlling entry for each product and being able to set bugs in a product to be totally read-only unless some group restrictions are met.
For each group, it is possible to specify if membership in that group is...
required for bug entry,
Not applicable to this product(NA), a possible restriction for a member of the group to place on a bug in this product(Shown), a default restriction for a member of the group to place on a bug in this product(Default), or a mandatory restriction to be placed on bugs in this product(Mandatory).
Not applicable by non-members to this product(NA), a possible restriction for a non-member of the group to place on a bug in this product(Shown), a default restriction for a non-member of the group to place on a bug in this product(Default), or a mandatory restriction to be placed on bugs in this product when entered by a non-member(Mandatory).
required in order to make any change to bugs in this product including comments.
To create Groups:
Select the "groups" link in the footer.
Take a moment to understand the instructions on the "Edit Groups" screen, then select the "Add Group" link.
Fill out the "Group", "Description", and "User RegExp" fields. "User RegExp" allows you to automatically place all users who fulfill the Regular Expression into the new group. When you have finished, click "Add".
The User Regexp is a perl regexp and, if not anchored, will match any part of an address. So, if you do not want to grant access into 'mycompany.com' to 'badperson@mycompany.com.hacker.net', use '@mycompany\.com$' as the regexp.
After you add your new group, edit the new group. On the edit page, you can specify other groups that should be included in this group and which groups should be permitted to add and delete users from this group.
Note that group permissions are such that you need to be a member of all the groups a bug is in, for whatever reason, to see that bug. Similarly, you must be a member of all of the entry groups for a product to add bugs to a product and you must be a member of all of the canedit groups for a product in order to make any change to bugs in that product.
