I installed sitecore 8.2 and after installation I logged in with admin account. Then i followed below procedure to create user and roles.
1) In the User manager I created one user - tom (not selected any role at this time, just selected domain as sitecore)
2) in the Role manager created new role (Devteam1).
3) using security editor assigned access rights "Read, Write an Inheritance" for all items in site content tree to Devteam1 role.
So I provided all access rights for Sitecore content,media library,layout etc..
4) Using Access Viewer I verified access right all are allowed in content tree items.
After this am trying to login with user tom, but I am getting an error:
You don't have access permission.
Then using the Security editor I applied access rights for the user also but no luck.
How to resolve this. What am doing wrong here?
