Allowing ACCESS to a new user for ONE project?

[Jiju Mathew]

Reading through previous posts is SO CONFUSING. 

How do I add a userA to an existing projectA ONLY? 

Please advise.

Hi, if you enter the project administration section, at the users & roles link you can add a user to a specific role in an specific project.

check then the groups the user has assigned, these groups may be grant access to other projects

So what I did: 

1. created a userA
2. Jira Admin > Projects > Project List -- clicked ProjectA

Now - the userA (when logging in) can see the two projects (ProjectA and ProjectB).  How do I grant userA to have access only to ProjectA?

check the user groups of user a, maybe the user is in a group that has granted the browse project permission in both projects.

the permission schemes can be shared between projects.

if thats the case, you have several options here:

1. create a new permission scheme, each one with a different group in the role that grants the browse permission, then add each user to the correct group
2. remove the group from the role that grants the browse project permission and manage the assigment of roles directly with users (not recommended, it does not scale)
