How does Stash resolve effective permissions when a user in multiple groups?

[Alex Jones]

If I have a user in multiple groups Read_Write and Read, and apply permissions at the project level How does stash resolve the effective permissions? Is it a basic union of the different permission sets, or is there some form of hierarchy/resolution order?

I skimmed through the permissions documentation in confluence, but I didn't see anything that seems to mention how this was resolved.

Repo permissions do not override Project permissions.  Project and Repo permissions are basically additive.  You will have the highest level of permission that any of your group memberships give you, whether that group was defined at the Project or Repo level.

This plugin is useful for seeing what the overall resulting set of permisons on a repo are: https://marketplace.atlassian.com/plugins/com.orbitz.stash.plugins.permission-viewer-plugin

Thank you for correcting me.

There are two level permission

1. Project Level
2. Repository level

I think, repository level permission overrides project level permission.

You can test as below.

1. Add group A to a repository, provide R permission.
2. Add group B to the project, provide RW permission.
   where the user is part of both groups, A and B

Your should have R only access to the repo under test, but RW access to other repos under the same project.

Hope this helps.

This is incorrect. Project permissions are just applied to all repos in that project. Lacking a 'write' or 'admin' permission on a repo will not override the user's project level permissions. Also, the question was about permissions from different groups at the project level. In which case the user will end up with the highest level of permission from any of their groups.

Thanks for the help!

I would suggest that you actually perform the test as described, because I have, and the results were not what Anurag thinks they would be.

I've done that one before, and agree with you. I was thanking you for your answer to his answer.
