I have just setup SSRS 2022 on one of my servers with my admin account (domain\user.admin). My admin account has 'Administrator' login on the server where SSRS 2022 is installed. So when I first login using my admin account, I am able to login without any issues.
Now I am trying to add my non admin account (domain\user) as administrator. When I add using Site Settings and then try to login with my non admin account to the Reports URL, I get HTTP 500 error.
Can someone help me to fix this issue? I am not sure where I am going wrong
Note: I have a domain level service account (not admin on server) setup as service account for SSRS.
Edit: This is what I have tried so far:
- This is a fresh install of SSRS 2022 (same happens with SSRS 2019 as well) and I have configured it with service account that has minimal permissions on server/DB instance level.
- After configuring, I can login to both ReportServer & Reports URL with my domain\user.admin account as this account is part of BUILTIN\Administrators group.
- I login to Reports URL and add my normal account (domain\user) as 'System user' in Site Settings and assign 'Content Manager' in Folder Settings. I also add my admin account (domain\user.admin) as 'System Administrator' in Site Settings. Once done, I have removed BUILTIN\Administrators from both Site Settings and Folder Settings.
- Then I logged out and when I login with my domain\user account, I get HTTP 500 error. But I can login fine with my domain\user.admin account.
- What is even more strange is, my teammate can login with his domain\user1.admin account (which is part of BUILTIN\administrators group) to Reports URL and can grant himself as 'System Administrator'. But his user account does not show up in 'Site Settings' or Folder Settings.
Is there any default option in SSRS 2019 or 2022 which enables 'BUILTIN\Administrators' to have full access? Also, why can't I access with an account which is not part of 'BUILTIN\Administrators' group?
