I confirmed the problem in the current trunk r17328.

Users cannot see some tabs in "Settings" tab if they don't have "Edit project", "Manage members", Manage versions" or "Manage issue categories" permission. For example, to access "Forums" tab, users should have one of those permissions in addition to "Manage forum" permission. I think the behavior inconsistent and illogical. Please see the following table for details.

|_. Tab |_. Required permission(s) |
| Project | _Edit project_ |
| Members | _Manage members_ |
| Issue tracking | _Edit project_ |
| Versions | _Manage versions_ |
| Issue categories | _Manage issue categories_ |
| Repositories | _Manage repository_ AND (_Edit project_ OR _Manage members_ OR _Manage versions_ OR _Manage issue categories_) |
| Forums | _Manage forums_ AND (_Edit project_ OR _Manage members_ OR _Manage versions_ OR _Manage issue categories_) |
| Time tracking | _Manage project activities_ AND (_Edit project_ OR _Manage members_ OR _Manage versions_ OR _Manage issue categories_) |

Here is a workaround for this issue.

I wrote a test of code written by Go MAEDA (#28693#note-3).
This test code will test that project settings and tabs are displayed according to permissions.

Setting target version to 3.3.8.
