Hi,

We're not able to apply a configuration setting on barbican configuration in our RHOSO 18 beta deployment even if it seems supported in the OpenstackControlPlane CRD.

Here a sample of the barbican section:

barbican:
apiOverride:
route: {}
enabled: true
template:

1. NOK
   nodeSelector:
   workload-type: stateless
   barbicanAPI:
   customServiceConfig: |
   [DEFAULT]
   max_allowed_secret_in_bytes = 1048576
   override:
   service:
   internal:
   metadata:
   annotations:
   metallb.universe.tf/address-pool: internalapi
   metallb.universe.tf/allow-shared-ip: internalapi
   metallb.universe.tf/loadBalancerIPs: 171.69.249.100
   spec:
   type: LoadBalancer
   replicas: 1
   nodeSelector:
   workload-type: stateless
   barbicanKeystoneListener:
   replicas: 3
   nodeSelector:
   workload-type: stateless
   barbicanWorker:
   replicas: 3
   nodeSelector:
   workload-type: stateless
   databaseInstance: openstack
   secret: osp-secret
   passwordSelectors:
   database: BarbicanDatabasePassword
   service: BarbicanPassword
   databaseUser: 'barbican'
   rabbitMqClusterName: 'rabbitmq'
   serviceUser: barbican

The parameter we wish to override is:
[DEFAULT]
max_allowed_secret_in_bytes = 1048576

I'm preparing a must-gather export in the meantinme.

Regards,
