A user with Admin (or Alpha) role logs in and then requests userinfo or the list of users via the paths /users/userinfo/ or /users/list/ and the relevant data is listed.

Actual results

A user with Admin (or Alpha) role logs in and then requests userinfo or the list of users via the paths /users/userinfo/ or /users/list/ and the user is then

2. the user see a the welcome screen
3. the requested userinfo or user list is not provided.

• [ x] I have reproduced the issue with at least the latest released version of superset.
• [x ] I have checked the issue tracker for the same issue and I haven’t found one similar.

Try flask fab create-permissions, this may mean you have set AUTH_TYPE on superset_config.py without setting PYTHONPATH.

[metaperl]

it created a new role, that is named the same as the username who is configured as admin in superset_config.py.

This occurred because AUTH_ROLE_ADMIN is set to a particular username.
