Documentation for JIRA 4.4. Documentation for other versions of JIRA is available too.
We are often asked the following:
How do we configure the system so that a user/user group can only register/see issues on one specific project?
In order to configure the above please follow the below instructions and tweak as necessary for your organization:
When users are created they are automatically a member of the jira-user group in order to allow them to login. The thing to note here is that the Default Permission Scheme grants users within the jira-user group certain permissions so those projects using the Default Permission Scheme will essentially give those users access to it.
It is also important to add that with the release of 3.7 and the introduction of Roles within JIRA it will not be necessary to create Groups for the above configuration.
For a detailed example using Group Permissions please see the following documentation: Using Project Level Security with User Groups
For a detailed example using Project Role's please see the following documentation: Using Project Level Security with Project Roles
