Using Tomcat, Keycloak and Bearer Token

[LucasPenido]

I'm having a problem configuring the apiman.properties that Tomcat uses. I set this conf so the Tomcat uses Keycloak:

# How the API Manager UI authenticates to the API Manager REST services
apiman-manager-ui.api.authentication.type=bearerToken
apiman-manager-ui.api.authentication.token.generator=io.apiman.manager.ui.server.kc.KeyCloakBearerTokenGenerator

# Security context settings.
apiman-manager.security-context.type=keycloak

But after accessing /apimanui and logging in using Keycloak, shows up like a login popup asking for another login, but none of the users I created work on this login. I would like to know how to remove this login popup.

PS: When using this configuration it works but with Auth-Token and I want to use Bearer Token:

# How the API Manager UI authenticates to the API Manager REST services
apiman-manager-ui.api.authentication.type=authToken
apiman-manager-ui.api.authentication.token.generator=io.apiman.manager.ui.server.auth.AuthTokenGenerator

# Security context settings.
apiman-manager.security-context.type=default
