Description of problem:

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


How reproducible:
Create several identity providers with "login: True" - master does not want to start and through error "Only one identity provider can support login".

However, it is possible to have few identity providers configured and login with "oc login".

Steps to Reproduce:

Expected results:
