Description of problem:

Pulp fails with Permission Denied.


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. create power_user
2. try to create another user with this power_user (without Administrator role for the first time!) **
3. it fails, okay
2. assign Administrator role to the power_user
3. try to create another user with this power_user again **

[**] $ katello --username power_user --password admin user create --username user_xxx --password admin

(you can do it in the UI -> same result)

Most likely user has been created without admin flag in pulp somehow (by mistake). We need to make it a transaction.
